A high-performance UV photodetector with superior responsivity enabled by a synergistic photo/thermal enhancement of localized surface plasmon resonance

Abstract

In this paper, we propose a new strategy to enhance the photoelectric performance of ultraviolet (UV) photodetectors by exploiting a synergistic photo-thermal effect which is induced by a localized surface...

A high-performance Ti3C2Tx/Lu2O3/GaN heterojunction deep ultraviolet photovoltaic photodetector enhanced via the dual-field coupling effect

“…An efficient method to improve the carrier separation efficiency is using the photo-induced pyroelectric effect that can be easily realized in low-dimensional materials/semiconductor devices. 22–27 Ti 3 C 2 T x is a typical two-dimensional material with the general chemical formula MXene (M n +1 X n T x ). 28 Due to its high photothermal conversion efficiency, this material has potential to exert synergistic effects for optimizing the performance of photodetectors.…”

Ag-modified enhance the performances of ZnO@CFs based omnidirectional photoelectrochemical ultraviolet detectors

“…Noble metal nanostructures modification on the surface of semiconductor materials is considered to be a straightforward and effective method to improve photoelectric detectors performance [12][13][14]. As a classical plasma of optical antenna, noble metal nanostructures present the unique ability to concentrate and amplify the intensity of incident light [15][16][17], for the localized surface plasmon resonance (LSPR) by the noble metal nanostructures interact with light of a certain wavelength [18][19][20][21]. The excitation of LSPR exhibits significant benefits for the performance of photoelectric detectors [19,22].…”

“…Construction of Au@Ag/AgCl Schottky contact by Li et al [24], a high-performance cysteine sensor was fabricated by changing the main LSPR characteristic, which provides more energy for carrier generation and enhances the photoelectric response of the Schottky contact. Zheng et al assembled UV photodetectors with high responsivity based on W 18 O 49 /TiO 2 nanofibers with a five-fold increase in responsiveness over the pure TiO 2 analog using the synergistic photothermal effect induced by LSPR [17]. Multi-wavelength recognizable photoamnesia detectors based on Ag NPs and SiO x nanocomposites by Han et al [25], relied on the effects of LSPR and optical excitation of Ag NPs in SiO x , the setup voltage of the detector was reduced.…”
