Detecting the light from different freedom is of great significance to gain more information. Two-dimensional (2D) materials with low intrinsic carrier concentration and highly tunable electronic structure have been considered as promising candidate for future room-temperature multi-functional photodetectors. However, current investigations mainly focus on intensity-sensitive detection; multi-dimensional photodetection such polarization-sensitive still in its early stage. Herein, intensity-...
Self-powered near-infrared detectors that can work without an external power source underpin important applications in versatile fields. Herein, a self-powered (NIR) detector with metal–semiconductor–metal structure was fabricated by mounting hydrothermal synthesized Te microwire onto Ti electrodes. Under 1550 nm illumination, the exhibits responsivity of 3.47 × 105 V/W and 170 mA/W detectivity 4 109 Jones at room temperature. Such competitive performance be attributed to built-in electric...
Abstract Due to the narrow bandgap, environment stability, and Pt vacancy‐induced magnetism, PtSe 2 has been considered a promising candidate for future broadband photodetection electronics. However, growth of single‐crystal is still challenge. Herein, synthesis hexagonal tetragonal 2H─PtSe flakes by precisely tailoring temperature reported. Through atomic structure analysis, are proven c ‐axis orientations , indicating preferred nucleation along basal plane vertically plane, respectively....
Achieving both a high power factor and low lattice thermal conductivity in thermoelectric (TE) materials has been longstanding challenge. Herein, we report significant advancements PbTe-based through band-sharpening approach that incorporates valley modification alongside an innovative core-shell structural strategy. The n-type AgxPb1-ySnyTe-0%Ag2Te compounds demonstrate substantial band sharpening, resulting exceptional electronic performance due to enhanced carrier mobility, despite...
Abstract Memory device is an important part of electronic equipment. 2D transition metal dichalcogenides that exhibit novel electrical characteristics hold promise in developing new types memory device. Here, the effect mica/WSe 2 heterostructure investigated. Under applying constant bias voltage and gate voltage, K + ions mica will migrate direction electric field be trapped to enable function. The gradient work as long‐range scatters electrostatically dope WSe channel. shift threshold...
Two-dimensional (2D) semiconductors have attracted great attention due to their rich electronic properties and even been considered the potential extend Moore's Law. However, Schottky barrier between metal 2D semiconductor is formed metal-induced gap states (MIGS), which greatly hinder development of transistors in large-scale integrated circuits. Meanwhile, most air-stable are nonmagnetic, limiting possibility spintronic application. Here, we report a new strategy suppress MIGS reduce...
Abstract Plasmonic lattice modes (PLM) on the periodic arrays of Au hemi-ellipsoids quartz substrates (inhomogeneous environment) is demonstrated experimentally. It found that formation PLM results from coupling between resonance and diffracted waves inside substrates. The quality factor can be attributed to three factors: weakening zero-order waves, strengthening hemi-ellipsoid’s match period nanoparticles’ wavelength. simulated show structural parameters, such as radius hemi-ellipsoid...
