Small signal analysis of MPCVD diamond Schottky diodes

Polycrystalline diamond (PCD) grown by chemical vapor deposition (CVD) is an intrinsic semiconductor particularly attractive for high power/high temperature devices. Nevertheless, the physical models for injection and transport of electrical carriers are remarkable complex and depend on the microstructure and composition of carbon species in the film. In this work, free-standing CVD PCD films were deposited by microwave plasma CVD (MPCVD) and...
