Abstract
Two material systems compete for detector applications in the DUV range, namely GaN and diamond. Whereas GaN with a direct bandgap is intensively studied for light emitting structures, diamond with an indirect bandgap has a long background as particle and X-ray detector. In this study, a diamond DUV-detector based on a MSM structure has been fabricated and characterized. Efficiency, speed and blindness to visible light have been investigated. A charge collection efficiency of approx. 100% at high electric field strength and an ultra fast response (FWHM <4 ns) could be demonstrated
