With the rapid development of information technology, the demand for miniaturization, integration, and intelligence of electronic devices is growing rapidly. As a key device in the non-von Neumann architecture, memristors can perform computations while storing data, enhancing computational efficiency and reducing power consumption. Memristors have become pivotal in driving the advancement of artificial intelligence (AI) and Internet of Things technologies. Combining the electronic properties of graphene with the size effects of quantum dots, graphene quantum dot (GQD)-based memristors exhibit potential applications in constructing brain-inspired neuromorphic computing systems and achieving AI hardware acceleration, making them a focal point of research interest. This review provides an overview of the preparation, mechanism, and application of GQD-based memristors. Initially, the structure, properties, and synthesis methods of GQDs are introduced in detail. Subsequently, the memristive mechanisms of GQD-based memristors are presented from three perspectives: the metal conductive filament mechanism, the electron trapping and detrapping mechanism, and the oxygen vacancy conductive filament mechanism. Furthermore, the different application scenarios of GQD-based memristors in both digital and analog types are summarized, encompassing information storage, brain-like artificial synapses, visual perception systems, and brain-machine interfaces. Finally, the challenges and future development prospects of GQD-based memristors are discussed. © 2025 The Royal Society of Chemistry.

Growing demands for precise current measurements, such as atto-ampere-level measurement of cross-cellular biological current transduction, have spotlighted a pressing need for low-noise resistors with ultra-high resistance immune to voltage fluctuations. Traditional semi-insulating materials, however, struggle to provide consistent resistance across varying voltages. To bridge this gap, we introduce a design that integrates semi-insulating 4H-SiC with atomic-level metal oxide interlayers and electrodes. The strategic adjustment of surface states via atomic-scale metal oxide layers optimizes the work functions on 4H-SiC surfaces, validated through density functional theory simulations. This design transcends conventional limitations, establishing an ideal Ohmic behavior and maintains Peta-Ohm-level resistance, unaffected by voltage variations. These on-chip devices with fine-tuned resistance are compatible with integrated circuit manufacturing processes, making them ideally suited for applications in precision electronics. © 2024, CC BY-NC-ND.

Optimizing the morphology and vertical phase distribution of the active layers is crucial for organic solar cells (OSCs). This study introduces [6,6]-phenyl-C61-pentyl acrylate (PC61PeA), a cross-linkable acrylated-based fullerene acceptor (FA), as the third component in the PM6:BO-4Cl binary system. The PC61PeA functions as a morphology modulator, which enhances the aggregation of donor and acceptor species while facilitates the separation of BO-4Cl molecules. Additionally, the crosslinking of PC61PeA establishes highly conductive pathways within the bulk heterojunction (BHJ) layers, thereby significantly enhancing the diffusion length of charge carriers and improves charge transport in the BHJ blend. Multiple measurements confirm the accumulation of PC61PeA molecules at the BHJ/MoO3 and BHJ/ZnO interfaces. As a result, the PM6:BO-4Cl:PC61PeA inverted device achieves a notable power conversion efficiency of 18.43%, surpassing the 16.14% efficiency of the PM6:BO-4Cl binary device. Importantly, the introduction of PC61PeA remarkably enhances the high-temperature (150 °C) thermal stability and UV-stability of OSCs. © 2024, The Authors. All rights reserved.

Photocatalytic methane combustion is a promising strategy to eliminate methane at ambient condition, but efficient photocatalysts are still lacking. Herein, we report that uniform anatase TiO2 nanocrystals predominantly enclosed with the {001} facets exhibit high activity in photocatalytic catalyzing methane combustion at RT in a flow-bed reactor. The photocatalytic methane reaction rate is 17.6 mmolCH4·h-1·gcatalyst-1, which is about 6 and 7 times of those catalyzed by TiO2 nanocrystals predominantly enclosed with the {100} facets or with the {101} facets. The valence band maximum and conduction band minimum were found to locate space-separately for TiO2-{001} nanocrystals terminated with the reconstructed (001)-(1 × 4) surface, at the surface and in the bulk, respectively. Meanwhile, the HOMO of methane adsorbed at the 4-fold-coordinated Ti4c site of reconstructed TiO2(001)-(1 × 4) surface is located at the valence band maximum of TiO2. Upon UV light illumination, TiO2-{001} nanocrystals exhibit spontaneous bulk-surface charge separation of photoexcited holes and electrons, leading to large concentrations of photoexcited holes on the surface, and subsequent facile interfacial hole transfer from TiO2(001) surface to adsorbed methane, leading to efficient methane combustion reaction. © 2022 American Chemical Society.

In this paper, we report a hybrid PEI/PEG-BP sensor (composite material of black phosphorus-organic framework-derived PEI/PEG nanohybrid) prepared by a one-pot method, in which the existence of PEI/PEG onto BP was confirmed by SEM, EDS, XPS and UPS. The gas sensing properties of the PEI/PEG-BP sensor, including the sensor response, response/recovery times, repeatability, selectivity, and effects of humidity on the sensor, were studied by exposure to several CO 2 gas concentrations ranging from 200 ppm to 300,000 ppm at room temperature (25 ℃). The results show that the PEI/PEG-BP sensor had an extremely wide detection range, with lower and upper detection limits of 200 ppm and 160,000 ppm, respectively. The response of the PEI/PEG-BP sensor to 200 ppm, and 160,000 ppm CO 2 gas at room temperature ( RT ) was 4.48%, and 254.02%, respectively, showing fast response/recovery time, excellent repeatability and high selectivity. The gas-sensing properties of the PEI/PEG-BP sensor are better than BP, PEI, PEG, PEI-BP and PEG-BP sensors. The superior properties of the PEI/PEG-BP sensor can be attributed to the BP framework, porous structure, electron doping, and surface reactive groups such as -NH 2 and -OH. The PEI/PEG-BP sensor, with its excellent gas-sensing performance will help us to further explore the changes of CO 2 concentration in microbial growth systems, natural environments, industrial production and so on. © 2022, The Authors.

Although fantastic milestones of Gallium nitride (GaN)-based materials in optoelectronic devices had been reached, the focus on the optimization of their geometrical structure for gas-sensing applications was relatively scarce. In this work, we demonstrated NO2 gas sensor based on p-type GaN hexagonal pits (GaN-HP) with high surface-to-volume ratio by wet etching method. The fabricated NO2 gas sensor had high sensitivity, high selectivity, fast response/recovery times. The response of p-type GaN-HP with etching time for 10 min to 2 ppm NO2 gas was 6.2%, which also have quick response and recovery time at room temperature. UV light drastically enhanced the response of p-type GaN-HP sensor by 1.3 times to 100 ppm NO2 . The gas sensing mechanism of p-type GaN-HP gas sensor was explored, which provided a theoretical and experimental basis for further research and development of high-performance gas sensors based on GaN material. © 2022, The Authors.

Designing new interface materials with the multifunctions of upper film crystallization control, interfacial defects passivation, and interfacial energy level regulation is crucial for developing efficient and stable perovskite solar cells (PSCs). Herein, a high polarity interfacial material, 2-cyano- N,N,N -trimethylammonium bromide (CNCB), was synthesized to engineer the buried interface between SnO 2 and perovskite of the PSCs. Comprehensive theoretical and experimental investigations demonstrate that CNCB interacts with perovskite precursors (PbI 2 and FAI) to regulate crystallization kinetics, yielding perovskite films with preferred orientation and reduced defects. Simultaneously, CNCB chemically interacts with both SnO 2 and perovskite surfaces, effectively passivating oxygen vacancies in SnO 2 and undercoordinated Pb 2 ⁺ defects at the perovskite buried surface. Furthermore, the high dipole moment of CNCB induces beneficial interfacial polarization, optimizing energy level alignment and suppressing non-radiative recombination. The CNCB-modified FACsPbI 3 PSCs achieve a champion power conversion efficiency (PCE) of 26.47% with exceptional operational stability, retaining 87.14% of their initial efficiency after 1000 h of continuous 1-sun illumination. This work establishes a molecular design paradigm for multifunctional interfacial materials in perovskite optoelectronics, highlighting the synergistic roles of crystallization control, defect passivation, and dipole engineering in high-performance devices.
