Among the many materials investigated for next-generation photovoltaic cells, organic–inorganic lead halide perovskites have demonstrated great potential thanks to their high power conversion efficiency and solution processability. Within a short period of about 5 years, solar cells based on these has increased dramatically from 3.8 over 20%. Despite tremendous progress in device performance, much less is known underlying photophysics involving charge–orbital–lattice interactions role...
Abstract Ferroelectric polarization switching and its domain evolution play a key role on the macroscopic electric properties of ferroelectric or piezoelectric devices. Mechanical has been reported recently in ~5 nm BaTiO 3 PbZr 0.2 Ti 0.8 O epitaxial films; however it is still challenge for mechanical force to switch slightly thicker film same way as an field. Here, we report that 70 BiFeO can be completely switched by similar observed with electrical switching. With gradual increase...
Two-dimensional (2D) ferroelectrics refer to those with layered structure and weak interlayer interactions (e.g., van de Waals coupling). A number of basic physical issues in the framework ferroelectricity deserve clarifications, one them is size effect regarding dependence on material thickness. In this work, we investigate ferroelectric domain structures 2D CuInP2S6 nanoflakes attached heavily doped Si wafers polarization switching using piezoresponse force microscopy. While shows highly...
Tin halide perovskites are rising as promising candidates for next-generation optoelectronic materials due to their good properties and relatively low toxicity. However, the high defect density easy oxidation of Sn2+ have limited performance. Herein, we report treatment FASnI3 (formamidinium tin, FA) perovskite film by a bifunctional cesium fluoride (CsF) additive, which improves quality significantly enhances photoelectric The responsivity perovskite-based photodetector (PD) with an optimal...
The ternary metal chalcogenide AgSbS2 has been regarded as a promising photovoltaic compound due to its excellent stability and nontoxicity. However, the response time of as-prepared photodetectors is longer by several orders magnitude than required for practical application, appealing an improving strategy alloy engineering. Herein, we fabricated AgSb1–xBixS2 (x = 0–0.5) investigated their photoresponse behaviors. In comparison with photodetector, AgSb0.7Bi0.3S2 photodetector demonstrates...
Abstract A linear polyurea (LPU) and a crosslinked (CPU) were respectively synthesized by condensation between 4,4′‐diaminodiphenyl methane multivariate isocyanates, then used as supporting material to load polyethylene glycol (PEG) for shape‐stabilized phase change materials (ssPCMs). LPU has an incompact flocculent morphology with higher surface area pore volume than CPU, CPU is composed of contiguous bead particles many interspaces. The shape stability PEG/CPU ssPCMs better that PEG/LPU...
P(VDF–TrFE) dipoles reduce ion migration and improve film stability via the interaction between ferroelectric ions in MAPbI 3 , enhance photoelectric performance of by reducing trap-assisted capture radius.
As a basic form of behavioral plasticity, habituation enables organisms to adjust their behaviors in response external stimulation and is fundamental ability organisms. The emulation hardware becomes critical highly efficient artificial neuromorphic computing. However, few devices can mimic because it includes two opposite responses the same repeated stimulus. Herein, we fabricate device Au/LiTaO3/Pt, which not only shows synaptic such as long-term potentiation/depression paired-pulse...
Hydrogels are composed of a three-dimensional network cross-linked hydrophilic polymer chains and large amounts water. The physicochemical properties the polymer-water interface in hydrogels draw our attention. Due to complex structure hydrogel systems, it is still challenge investigate interfacial layer through experiments. In this work, we covalently bonded chitosan-based ice-hydrogels by dielectric relaxation spectroscopy (DRS) techniques presence avoided electrode polarization. DRS data...
