Journal ArticleDOI
Polycrystalline diamond photoconductive device with high UV-visible discrimination
TL;DR: In this article, an interdigitated electrode design with spacings of 20 μm was used to produce effective UV photodetecting devices at bias values in the range 0.1-10 V.
Journal ArticleDOI
Photoconductive properties of thin film diamond
TL;DR: In this paper, the origin of photoconductivity within diamond is briefly reviewed, and several applications for thin film diamond formed by chemical vapour deposition (CVD) could be realised if the extrinsic photoconductive response could be controlled, including the fabrication of deep UV photodetectors which are “blind” to visible light.
Journal ArticleDOI
Thin film diamond photodiode for ultraviolet light detection
TL;DR: In this article, a photodiode was constructed from lightly boron doped, Si supported, thin film chemically vapor deposited (CVD) diamond which showed over five orders of magnitude discrimination between deep UV (≤220 nm) and visible light.
Journal ArticleDOI
Cleaning thin-film diamond surfaces for device fabrication: An Auger electron spectroscopic study
TL;DR: Auger electron spectroscopy was used to analyze polycrystalline thin-film diamond surfaces following the use of differing methods for the removal of unwanted non-iamond carbon as discussed by the authors, which is effective for producing a surface that gives an Auger spectrum typical of diamond with little contamination.
Journal ArticleDOI
Thin film diamond UV photodetectors: Photodiodes compared with photoconductive devices for highly selective wavelength response
TL;DR: In this paper, a planar interdigitated design with 20-μm electrode spacings was found to offer unprecedented wavelength discrimination between deep UV and visible light, with dark currents.
