Abstract :
The paper is concerned with the investigation of the UV detection performances of 6H-SiC Schottky and junction barrier diodes with oxide ramp termination. The devices exhibit a high responsivity in UV spectral range with excellent visible rejection ratio. An accurate model for the determination of the quantum efficiency is developed. Excellent agreement between model and simulated data is achieved.
