Validation of SiC photodetectors response

Abstract

In recent years, great interest in ultra-violet (Uv) photodetectors arises due to a wide-ranging of applications including flame sensing [l], missile sensing, biological agent detection, detection of celestial objects, and in the field of particle physics. Currently, silicon (Si) is the favour material used in the fabrication of UV detectors. The maindraw back of Si UV detectors is due to the undesirable response to visible light. For Si photodetector to respond only to UV radiation, special external filters must be employed. Unfortunately, this filtering process reduces the Si responsivity by several orders of magnitude.
