Resistive random-access memory (RRAM) is one of the most promising candidates for next-generation nanoscale nonvolatile memory devices and neuromorphic computing applications. In this study, we developed a novel mixed-dimensional design for RRAM devices, incorporating zero-dimensional quantum dots (QDs), two-dimensional MoS2, and a TiO2 switching layer to achieve prominent interfacial switching behaviors. Compared with typical filamentary RRAM devices, the proposed heterostructure featured a light-sensitive QDs/MoS2 layer that allowed for bias-controllable resistive changes during the set and reset processes without abrupt switching. This was endowed by effective electron-hole pair separations upon excitation and the generation of a thin molybdenum oxide (MoOx) layer due to the accumulation of oxygen ions at the interface between MoS2 and TiO2. The ITO/QDs/MoS2/TiO2/Pt RRAM device exhibited an on/off ratio of 10 with improved endurance under 515 nm laser illumination and wavelength-dependent resistive switching behavior, making it useful for multilevel storage. Furthermore, the heterostructured device demonstrated synaptic characteristics with enhanced potentiation and depression nonlinearities and asymmetry factors, revealing its potential for future neuromorphic applications. © 2024 American Chemical Society.

Non-Hermitian Mott Skin Effect

引用

Physical Review Letters 2024年第7期133卷 076502-076502页

作者： Tsuneya Yoshida Song-Bo Zhang Titus Neupert Norio Kawakami Department of Physics Institute for Theoretical Physics Hefei National Laboratory Hefei Anhui 230088 China International Center for Quantum Design of Functional Materials (ICQD) Department of Materials Engineering Science Fundamental Quantum Science Program TRIP Headquarters

We propose a novel type of skin effects in non-Hermitian quantum many-body systems that we dub a “non-Hermitian Mott skin effect.” This phenomenon is induced by the interplay between strong correlations and the non-Hermitian point-gap topology. The Mott skin effect induces extreme sensitivity to the boundary conditions only in the spin degree of freedom (i.e., the charge distribution is not sensitive to boundary conditions), which is in sharp contrast to the ordinary non-Hermitian skin effect in noninteracting systems. Concretely, we elucidate that a bosonic non-Hermitian chain exhibits the Mott skin effect in the strongly correlated regime by closely examining an effective Hamiltonian. The emergence of the Mott skin effect is also supported by numerical diagonalization of the bosonic chain. The difference between the ordinary non-Hermitian skin effect and the Mott skin effect is also reflected in the time evolution of physical quantities; under the time evolution spin accumulation is observed while the charge distribution remains spatially uniform.

The sinterability and interfacial stability issues in the composite cathode have been the main bottlenecks of oxide-based all-solid-state Li battery development. The interfacial reaction between the electrode and electrolyte plays an important role in the sinterability and interfacial stability of a composite cathode. A suitable interfacial reaction can not only improve the sinterability by providing an additional driving force for chemical bond formation, but it can also stabilize the electrode/electrolyte interface by forming interfacial reaction products which remain stable during operation of the cell. In this work, a suitable dopant that can induce the formation of the desired interphase between the LiNi0.5Mn1.5O4 cathode and Li0.33La0.55TiO3 electrolyte was obtained through ab inito computational screening. Experimental verification was carried out by field-assisted sintering technology/spark plasma sintering (FAST/SPS) for obtaining mechanically stable composite cathode pellets and heat treatment for inducing the interfacial reaction. The dopant identified by computation was proven to induce the in situ formation of a stable protective layer. A successful method of simultaneously improving sinterability and interfacial stability in an oxide-based composite cathode is demonstrated in this work. © 2024 The Royal Society of Chemistry.

Hypothesis: Aqueous zinc-ion batteries (AZIBs) have received considerable attention owing to their safety, low cost, and environmental benignity. However, the side reactions of hydrogen evolution revolution and Zn dendrite growth reduce the Coulombic efficiency and life span of AZIBs. To address these issues, we designed an artificial protective layer of a Te-hybridized core–shell zeolitic imidazolate framework (ZIF). Experiments: A core–shell structure of ZIF-8@ZIF-67 was first developed as a protecting layer on the Zn anode. To improve the poor conductivity of ZIF and its affinity for Zn, the core–shell structure was hybridized with zincophilic Te to increase the surface area and reduce the charge-transfer resistance. Findings: By incorporating metallic Te into ZIF-8 and ZIF-67, the nucleation potential and charge-transfer resistance were significantly reduced, enhancing the ion reaction kinetics and electron migration. Benefiting from the Te-hybridized ZIF-8@ZIF-67-derived nitrogen-doped porous carbon (Te-hybridized ZIF-8@ZIF-67/NC) layer, a full cell of Zn coated with Te-hybridized ZIF-8@ZIF-67/NC//MnO2 exhibited an excellent rate performance of 214 mAh g−1 at an ultrahigh current density of 10 A g−1 and ultralong cycle life (3200 cycles) without the formation of Zn dendrites. © 2023 Elsevier Inc.

We study size- and charge-asymmetric oppositely charged colloids driven by an external electric field. The large particles are connected by harmonic springs, forming a hexagonal-lattice network, while the small particles are free of bonds and exhibit fluidlike motion. We show that this model exhibits a cluster formation pattern when the external driving force exceeds a critical value. The clustering is accompanied with stable wave packets in vibrational motions of the large particles.

Catalyst characteristics such as specific surface area, porosity and active site play an essential role in catalyst design. Understanding of the characteristic functions in controlling catalyst activity is necessary for considering the catalyst application, especially the Ni-loaded lignite char catalyst, employed in catalytic steam gasification. In this work, the unmodified and five modified catalysts were used to study the effect of catalyst characteristics on their performance for catalytic steam gasification of coal in the two-stage fixed-bed reactor. The findings indicated that the fresh acid modified catalysts increased specific surface area and micropore formation, including the smaller Ni metal crystallite size, the decreasing of Ni metal nanoparticle size and the well-dispersed of Ni metal nanoparticles. Meanwhile, the fresh modified catalysts by the alkali and the combined alkali-acid treatments promoted mesopore formation. Enhancing catalytic steam gasification of coal, it was found that the mesoporosity of catalyst was the considerable initial characteristic for controlling the catalyst activity. The total gas yields of the mesoporous catalysts were in the range of 50.65–77.70 mmol/gVM,feed, while the total gas yields of the microporous catalysts were 43.82–55.34 mmol/gVM,feed. After catalyst testings, the specific surface areas and number of mesopores in the spent catalysts were increased by steam. Remarkably, these changing pore sizes affected the transformations of the isotherms (type I + II to type II) and the hysteresis loops (type H4 to type H3). Also, steam influenced the conversion of Ni metals to NiO, Ni(OH)2 and Ni2O3. For thermal property, all spent catalysts had high thermal stability. The modified catalysts could decrease carbon deposition more than the unmodified catalyst, which was an upside for catalyst reusability. © 2022 Energy Institute
