Abstract Recent progress in two-dimensional ferroelectrics greatly expands the versatility and tunability van der Waals heterostructure based electronics. However, switching endurance issue that widely plagues conventional practical applications is hitherto unexplored for layered ferroelectrics. Herein, we report observation of unusual polarization fatigue behaviors CuInP 2 S 6 , which also possesses finite ionic conductivity at room temperature. The strong intertwinement short-range...
Abstract Ferroelectric van der Waals (vdW) heterostructure have recently emerged as a low‐power, versatile device paradigm because it combines the great diversity of 2D materials and memory nature ferroelectrics. The non‐volatile field effect generated by polarization bound charge is pivotal factor for device's performance. Unfortunately, microscopic studies on interplay between switching electrostatic coupling at heterojunction remain largely overlooked. Herein, authors investigate...
Recent success in exfoliating violet or Hittorf's phosphorus down to monolayer reignites the research passion this ancient yet mysterious material, questing for superior electronic and optoelectronic functionalities. Unfortunately, poor air stability that plagues black also exists counterpart. Aiming provide more insight into degradation chemistry accordingly find a facile solution it, herein, we employ concerted elemental, chemical vibrational spectroscopies reveal critical role of oxygen...
To improve the permeability of wood, three chemical reagents were used to pretreat Chinese fir, white oak, and poplar. Through a factorial experiment with mass change rate wood as indicator, NaOH was preliminarily selected pretreatment agent. Further orthogonal experiments conducted explore effects concentration, temperature, treatment time on rate, dye uptake transverse penetration color difference wood. A fuzzy, comprehensive analysis optimize process. The results showed that after...
Wood staining can improve the quality of Chinese fir. In this study, Cinnamomum camphora natural plant pigment was used as a substitute for synthetic dyes to stain fir, and performance enhanced through pre-mordanting with alum. The dyeing effects direct mordant were compared, factors levels influencing color difference, wash fastness, light fastness investigated an orthogonal experimental design. results showed that mordanting time had greatest influence on difference lightfastness, while...
Ionic migration in solid phases is actively explored as a mechanism for neuromorphic computing elements, example, but direct imaging of the ionic and its correlation with macroscopic electronic transport are tricky. Through multiple state-of-the-art microscopy techniques authors visualize Ag${}^{+}$ AgBiP${}_{2}$Se${}_{6}$, how it modulates interfacial barrier to induce switchable diodelike device. Illuminating device can be used switch off tunability, expanding functionality. These results...
Transition metal thiophosphate, CuInP2S6 (CIPS), has recently emerged as a potentially promising material for photoelectrochemical (PEC) water splitting due to its intrinsic ferroelectric polarization spontaneous photocarrier separation. However, the poor kinetics of hydrogen evolution reaction (HER) greatly limits practical applications. Herein, we report self-enhancing photocatalytic behavior CIPS photocathode chemically driven oxygen incorporation by photoassisted acid oxidation. The...
Metal thiophosphates have recently received increasing research interest, thanks to their diversity in regard metal cation occupation within the P–S scaffold, which produces a broad array of functional properties. Among them, In4/3P2S6 belongs special case as regards ordering cations and vacancy sites, whose physical properties remain largely unexplored, especially atomically thin limit. In this work, we undertake comprehensive investigation on thickness-dependent optical vibrational from...
Bismuth vanadate (BVO4, BVO) is a promising and widely studied photoanode material for photocatalytic water splitting. However, little research devoted to its photodetection properties. Herein, phase-pure BVO-film photodetector was successfully fabricated by depositing polycrystalline BVO film through magnetron sputtering postannealing treatment. The grain size distribution the boundary density modulation could result in better performance, basic mechanism of photocurrent optimization...
