UV Laser Beam Profilers Based on CVD Diamond
1D and 2D detector arrays have been realized on 270 μm thick 10 × 10 mm2 CVD diamond samples. The relatively high resistivity of diamond specimens in the dark (>3 × 1012 Ωcm) allowed the fabrication of photocondu...

UV Schottky Sensors Based on Wide Bandgap Semiconductors
Planar Al/GaN/Ni Schottky diodes were realized on GaN films deposited on sapphire substrates and characterized in the dark and under illumination. The optoelectronic characteristics of GaN photodetectors appea...

Photoconductive Position Sensitive CVD Diamond Detectors
Different contact structures were studied to realize CVD-diamond sensors able to detect light beam displacements. Photons irradiate the sample backside where a mesh contact is used for device biasing. Photogen...
