Extensive studies have focused on degradation of perovskite at low charge carrier density (16cm-3), but few have surveyed the degradation mechanism at high charge carrier density (∼1018cm-3). Here, we investigate the degradation mechanisms of perovskite under high charge carrier conditions. Unlike the observations in previous works, we find that MAPbI3degradation starts at surface defects and progressing from the surface defects towards neighboring regions under high charge carrier density condition. By using PbI2passivation, the defect-initiated degradation is significantly suppressed and the nanoplatelet degrades in a layer-by-layer way, enabling the MAPbI3laser sustain for 4500 s (2.7×107pulses), which is almost 3 times longer than that of the nanoplatelet laser without passivation. Meanwhile, the PbI2passivated MAPbI3nanoplatelet laser with the nanoplatelet cavity displaying a maximum quality factor up to ∼7800, the highest reported for all MAPbI3nanoplatelet cavities. Furthermore, a high stability MAPbI3nanoplatelet laser that can last for 8500 s (5.1×107pulses) is demonstrated based on a dual passivation strategy, by retarding the defect-initiated degradation and surface-initiated degradation, simultaneously. This work provides in-depth insights for understanding the degradation of perovskite at high charge carrier density. Copyright © 2021, The Authors. All rights reserved.

Organic photodetectors (OPDs) possess bright prospects in applications of medical imaging and wearable electronics due to the advantages such as low cost, good biocompatibility, and good flexibility. Photomultiplication OPDs (PM-OPDs) enabled by the trap-assisted carrier tunneling injection effect exhibit external quantum efficiencies far greater than unity, thus the acquired responsivities are extremely high. However, the reported PM-OPDs with high responsivity performances are all accompanied by high dark currents due to the introduction of carrier traps, which inevitably results in inferior detectivities. In this work, we modify a P3HT:PCBM donor-rich PM-OPD by introducing an atomically thin Al2O3 interfacial layer through the ALD technique, obtaining a high responsivity of 8294 A/W and high detectivity of 6.76×1014 Jones, simultaneously, both of which are among the highest reported for bulk heterojunction PM-OPDs. Ascribed to the introduction of the atomically thin Al2O3 layer, the metal-insulator-semiconductor (MIS) tunneling junction is formed, which brings forward a suppressed dark current along with an increased amounts of holes tunneling under forward bias. Meanwhile, the weak light detection limit of the modified PM-OPD within the linear response range reaches the level of nW/cm2. Based on the proposed PM-OPD, a proof-of-concept image sensor with 26×26 pixels is demonstrated, which can respond to both ultraviolet light and visible light. The PM-OPD based sensor arrays can find broad applications for medical imaging, wearable electronics, etc. Copyright © 2021, The Authors. All rights reserved.

Gallium nitride (GaN) has some challenges for gas sensing, such as high detection lower limit (LOD) or controlling the epitaxy of nanostructures. To address these issues, we exclusively designed a device to enhance the gas interaction capabilities of GaN quantum dots (QDs) film fabricated by metal-organic chemical vapor deposition (MOCVD). The GaN QDs film gas sensor exhibited a low LOD (5 ppb) to NO2 at room temperature (RT), which has much superior gas performance than other GaN-based sensors. The results manifest that many ultra-small QDs around 2 nm in diameter are stacked to form QDs of larger size, and confirm the existence of vacancies. The sensor displays a ultra-high electron mobility of 1237.37 cm2 V−1s−1, demonstrate that great shallow donor impurities in GaN QDs film that ionize easily at RT, which is greatly beneficial for gas sensing. The sensing mechanisms were analyzed based on its abundant active sites, ultrahigh carrier mobility, high surface energy and chemical activity, grain boundary barrier and good electrical conductivity. Moreover, the sensor processes high selectivity, repeatability, stability and reusability based on MOCVD technology which can realize precise control of structure, morphology and surface energy level, which is expected to achieve rapid industrialization. © 2022, The Authors.

Water pollution is a serious problem around the world. It causes the lack of clean drinking water and brings risks to human *** technology has become a competitive candidate to treat the contaminated wastewater due to its high separation efficiency and low energy consumption. In this review, we introduce the recent development of several kinds of bioinspired separation membranes, involving the membrane design and applications. We emphasize the multi-phase liquid separation membranes inspired from nature with special wettability applied for oil/water separation, organic liquids mixture separation, and emulsion separation. After separating multi-phase liquids using these membranes, small molecule pollutants still exist in singlephase liquid. Therefore, we also expand the scope to small molecule-scale separation membranes, such as the nacre-like graphene oxide separation membrane and other nanofiltration membranes. Summary and outlook concerning the future development of separation membranes are also introduced briefly.

Research on two-dimensional(2D) materials has been explosively increasing in last seventeen years in varying subjects including condensed matter physics, electronic engineering, materials science, and chemistry since the mechanical exfoliation of graphene in 2004. Starting from graphene, 2D materials now have become a big family with numerous members and diverse categories. The unique structural features and physicochemical properties of 2D materials make them one class of the most appealing candidates for a wide range of potential applications. In particular, we have seen some major breakthroughs made in the field of 2D materials in last five years not only in developing novel synthetic methods and exploring new structures/properties but also in identifying innovative applications and pushing forward commercialisation. In this review, we provide a critical summary on the recent progress made in the field of 2D materials with a particular focus on last five years. After a brief backgroundintroduction, we first discuss the major synthetic methods for 2D materials, including the mechanical exfoliation, liquid exfoliation, vapor phase deposition, and wet-chemical synthesis as well as phase engineering of 2D materials belonging to the field of phase engineering of nanomaterials(PEN). We then introduce the superconducting/optical/magnetic properties and chirality of 2D materials along with newly emerging magic angle 2D superlattices. Following that, the promising applications of 2D materials in electronics, optoelectronics, catalysis, energy storage, solar cells, biomedicine, sensors, environments, etc. are described sequentially. Thereafter, we present the theoretic calculations and simulations of 2D materials. Finally, after concluding the current progress, we provide some personal discussions on the existing challenges and future outlooks in this rapidly developing field.

Heptamethine cyanine dyes are promising candidates for near-infrared (NIR) filters in CMOS image sensors due to their sharp NIR absorption and high visible light transmittance. However, their practical application is limited by narrow spectral coverage and poor thermal stability. In this study, a series of benzo[ cd ]indolenyl-substituted cyanine dyes with varied meso-position substituents were synthesized to achieve broad NIR absorption across 700–1100 nm. Density functional theory calculations revealed that nitrogen-linked substituents introduced a bis-dipolar electronic structure, enhancing absorption in the intermediate NIR region (800–950 nm). The incorporation of the weakly coordinating anion, tetrakis(3,5-bis(trifluoromethyl)phenyl)borate, improved thermal stability and mitigated aggregation of the dyes. Thermal stability analysis revealed that the planarity of the polymethine backbone is a key factor determining their isothermal stability within the film matrix. NIR-absorbing films with broad and continuous coverage across the entire 700–1100 nm range were successfully fabricated through the strategic combination of multiple cyanine dyes with complementary absorption bands.

Aligning the intrinsic photocatalytic activities of various types of TiO₂ facets is of great importance and interest in TiO₂ photocatalysis. Herein, we report a comparative study of the intrinsic photocatalytic activities of anatase TiO₂(001)-(1 × 4) and rutile TiO₂(110)-(1 × 1) surfaces probed by photostimulated desorption of O₂ with combined thermal desorption spectroscopy, photostimulated desorption spectroscopy, and density functional theory calculations. Photostimulated desorption behavior of O₂ depends on both TiO₂ surface structures and O₂ adsorption configurations. O₂ species adsorbed on the anatase TiO₂(001)-(1 × 4) surface exhibit a higher intrinsic photostimulated desorption reactivity than those on the rutile TiO₂(110)-(1 × 1) surface, which can be associated with their electronic structures and subsequent hole transfer processes from TiO₂. These results provide, for the first time, direct and unambiguous experimental evidence for the higher intrinsic photocatalytic activity of the anatase TiO₂(001) facet than those of other TiO₂ facets and highlight the key role of structures of both TiO₂ surfaces and adsorbed species in TiO₂ photocatalysis.

Vinylen verbrückte zwei-dimensionale Polymere (V-2DPs) und deren schichtgestapelten kovalent organische Gerüstverbindungen (V-2D COFs) zeichnen sich durch ihre hohe π-Konjugation in der Ebene und ihre robuste Struktur als vielversprechnende Kanidaten für energiebezogene Anwendungen aus. Allerdings sind derzeitige syntheisische Ansätze auf die Herstellung von V-2D COF Pulver beschränkt, welche schlecht prozessierbar sind, was die Integration in Geräte, insbesondere für Membranthechnologien, welche auf dünnen Filmen beruhen erschwert. Im folgenden berichten wir über die neu-artige Synthese von kationischen 2DPs-Filmen an der Wasseroberfläche, die über Vinyleneinheiten verbrückt sind ( V-C2DP-1 und V-C2DP-2 ) mittels Knoevenagel-Polykondensation, diese dienen als anionenselektive Elektrodenbeschichtung für hochreversible und langlebige Zink-basierte Dual-Ionen-Batterien (ZDIBs). Modellreaktionen und theoretische Modellierung zeigen eine erhöte Reaktivität und Reversibilität der Knoevenagel-Reaktion an der Wasseroberfläche an. Basierend darauf zeigten wir die 2D Polykondensation hin zu V-C2DP-Filmen an der Wasseroberfläche, welche eine weitreichen-de laterale Größe, anpassbare Dicke und hohe chemischer Stabilität besitzen. Repräsentativ zeigt sich V-C2DP-1 als ein vollständig crystalliner und flächen-orientierter Film mit den in der Ebene liegenden Gitterparametern von a =b≈43.3 Å. Dank der gut definierten katinoischen Funktionalitäten, orientierten 1D-Kanälen und des sabilen Gerüstes besitzt der V-C2DP-1 Film eine herausragende Transportselektivität von Bis(trifluormethansulfon)imid-anion (TFSI − ) (Transferrate, t =0.85) für die Graphitkathode in Hochspannungs-ZDIBs. Die hohe Selektivität führt zu zusätzlichen TFSI − -Intercalationsstufen wodurch eine höhere spezifischen Kapazität (von ~83 bis 124 mAh g −1 ), sowie Zyklusdauer (>1000 Zyklen, 95 % Kapazitätserhaltung) gefördert wird.
