High Performance Flexible Visible-Blind Ultraviolet Photodetectors with Two-Dimensional Electron Gas Based on Unconventional Release Strategy

Visible blind p+-π-n--n+ ultraviolet photodetectors based on 4H-SiC homoepilayers

p–p–n –n ultraviolet photodetectors based on 4H–SiC homoepilayers have been presented. The growth of the 4H–SiC homoepilayers was carried out in a LPCVD system. The size of the active area of the photodetectors was 300 300mm. The dark and illuminated I–V characteristics had been measured at reverse biases form 0 to 20V at room temperature, and the illuminated current was at least two orders of ...

High-performance flexible photodetectors based on GaTe nanosheets.

2D layered GaTe materials have attracted a great deal of attention for optoelectronic applications due to their direct band structure, whether in bulk or as a single layer. In this paper, for the first time, we have synthesized high quality, single crystalline GaTe nanosheets by employing a facile CVD method. The size of the GaTe nanosheets reached several tens of micrometers, and some of them ...

Carrier Transport in High-Speed Photodetectors Based on Two-Dimensional-Gas

Single-crystalline In2S3 nanowire-based flexible visible-light photodetectors with an ultra-high photoresponse.

With a band gap of 2.28 eV, In2S3 is an excellent candidate for visible-light sensitive photodetectors. By growing single-crystalline In2S3 nanowires via a simple CVD method, we report the fabrication of high-performance single-crystal In2S3 nanowire-based flexible photodetectors. The as-fabricated flexible photodetectors exhibited an ultra-high Ion/Ioff ratio up to 10(6) and a high sensitivity...

Aluminum Gallium Nitride-based Solar-blind Ultraviolet Photodetectors

Dedication To my parents, Gary and Carol, and to my loving girlfriend Connie. v Acknowledgements I would like to express my gratitude to my supervising, Professor Joe C. Campbell, for showing me the exciting world of nitride-based optoelectronic devices. His wise advice and constant support has been the most important aspect of my research, inspiring all of the work I have accomplished. Joe Cam...
