Pyro-phototronic effect enhanced broadband photodetection based on CdS nanorod arrays by magnetron sputtering

Abstract

In this work, self-powered photodetectors (PDs) based on RF magnetron sputtering-fabricated CdS nanorod arrays and polished Si substrates were prepared for the first time.

High‐Performance UV Photodetector via Energy Band Engineering and LSPR‐Enhanced Pyro‐Phototronic Effect in Au Decorated 2D‐PbI2/1D‐ZnO Heterojunction

“…Then, the temperature of materials is increased after multiple illuminations, which decreases the temperature change and pyroelectric current slightly. [42,54,55] In terms of time parameters, the response time (𝜏) refers to the duration required for the output current of the photodetector to reach a stable response value or return to its pre-irradiation level. The rise time (𝜏 r ) refers to the duration time required for photocurrent to increase from 10% to 90%, while the fall time (𝜏 f ) represents the duration time for the photocurrent to decrease from 90% to 10%.…”

Recent Advances in Electrospun Metal Chalcogenide Anodes for Lithium-Ion and Sodium-Ion Batteries

“…Typical VIB-based sulfides anodes, such as MoS 2 and W x S y with the benefits of 2D-layer structure and high capacity, have attracted a lot of interest in the field of LIBs and SIBs. However, their rate capability and cycling stability are usually limited by their poor electronic conductivity, large volume variation, and irreversible polysulfide dissolution. , The carbon fiber produced by electrospinning can successfully improve the conductivity and structure stability. For example, Yan et al prepared expanded MoS 2 nanosheets grown on nitrogen-doped branched TiO 2 /C.…”

Annealing effect on the pyro-phototronic behaviour in Al/nanostructured PS-ML: p+-Si Schottky photovoltaic device

“…The pyroelectric effect and the photovoltaic effect couple together, to develop a new mechanism called pyro-phototronic effect [1][2][3][4][5][6][7][8][9], which has an excellent role in enhancing device photo sensing performance. It is now well-known phenomenon which contributes specifically for enhanced UV sensing purpose and basically observed in materials with noncentro symmetric crystal structure like ZnO, CdS, GaN and some organic materials like crystalline rubrene [10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27]. The phenomenon has been first observed by Z. Wang et al [28] in perovskite ZnO nanowires heterojunction-based photodetector.…”
