Photoconductor Diamond Film Detector

Diamond film was synthesized on a silicon substrate by MPCVD (microwave plasma chemical vapor deposition) process and used to fabricate a photoconductor for the detection of UV light. The photoconductor was fabricated on free standing diamond film and operation in a planar. This paper presents the spectral response of photoconductor, concentration of boron doping, times and temperature. The device shows good response to UV light and a very low response to visible light. Furthermore, the device reveals little change in spectral response with increasing temperature at all wavelengths.
