Abstract
A porous-SiC thin-film photodetector with a pn junction structure has been successfully fabricated on a Si substrate. The developed device exhibits a high responsivity of 0.4 A/W at 25°C for 650 nm irradiation. In particular, the device has a responsivity of 0.35 A/W and a photo/dark current ratio larger than 100 at 200°C, indicating its potential capability for high-temperature operation
