Interfacial coupling of Z-scheme CsSnBr 3 /SnS 2 heterostructure induces a narrowing band gap and reduces carrier recombination rate. Coupling interface Br vacancy defects has excellent photovoltaic performance.
A strong Fermi level pinning (FLP) effect can induce a large Schottky barrier in metal/semiconductor contacts; reducing the height (SBH) to form an Ohmic contact (OhC) is critical problem designing high-performance electronic devices. Herein, we report interfacial features and efficient modulation of (ShC) OhC for MoSi2N4/M3C2 (M = Zn, Cd, Hg) van der Waals heterostructures (vdWHs). We find that vdWHs p-type ShC with small SBH calculated factor S ≈ 0.8 contacts. These results indicate FLP be...
Exploring and designing an efficient S-scheme heterojunction photocatalyst for water splitting are crucial. Herein, we report the interfacial electronics, photoexcited carrier dynamics, photocatalytic performance of MoSi2N4/SnS2 van der Waals under modulation electric field biaxial strain.

Abstract A flexible metal‐free flash memory device with reduced graphene oxide films as electrodes and diarylfluorene‐based π‐conjugation‐interrupted hyperbranched polymers (CIHPs) active switches is reported. Two CIHPs, named PCzPF PCzPF‐PF, are synthesized via BF 3 •Et 2 O‐catalyzed fluorenol’s Friedel–Crafts reaction, where the PCzPF‐PF designed by decoration of hindrance functional groups, i.e., bulky 9‐phenyl‐fluorenyl (PF) moieties, at end‐groups PCzPF. Both two CIHPs exhibit excellent...
The pivotal role of magnetic anisotropy in stabilising two-dimensional (2D) magnetism has been widely accepted, however, direct correlation between and long-range ordering the 2D limit is yet to be explored. Here, using angle- temperature-dependent tunnelling magnetoresistance, we report unprecedented metamagnetic phase transitions atomically-thin CrOCl, triggered by easy-axis flipping instead conventional spin flop mechanism. Few-layer CrOCl devices various thicknesses consistently show an...
Sn‐based perovskite materials with nontoxic, low cost, and unique structure have attracted much attention. However, their efficiency only reaches 14.09% due to the higher carrier recombination rate short lifetime in photovoltaic applications. Herein, interfacial electronic structure, optical absorption, charge transfer mechanism, performance of CsSnBr 3 /MoSe 2 heterostructure are systematically investigated by theoretical calculation experimental observation. The results indicate that...
