High Responsivity UV Photoconductors Based on GaN Epilayers
Abstract
This paper will describe a new ultraviolet (UV) sensitive photoconductive detector based on gallium nitride (GaN) Material. Data will be presented on devices fabricated over the past several months. These devices have a high responsivity between 200 to 360 NM with a sharp long wavelength cutoff at 360 NM. The detectors have measured gains in excess 6000 and frequency responses of greater than 100 Hz. The devices have measured dynamic ranges of over four orders of magnitude and operate with bias voltages of 5 to 10 volts. Device designs will be shown that can be utilized in the development of a large monolithic focal plane for UV imaging
