This invention relates to a p-type doped CVD diamond Schottky radiation detector and its fabrication method. The detector comprises a metal electrode layer, an intrinsic diamond layer, a p-type doped diamond layer, and an HPHT diamond substrate. These layers are stacked in a layered structure from top to bottom. The metal electrode layer serves as the top electrode, forming a Schottky contact with the intrinsic diamond layer. The intrinsic diamond layer, serving as the core functional region for radiation detection, is grown using a homoepitaxial CVD process. The p-type doped diamond layer, serving as the back contact layer, is grown on the surface of the HPHT diamond substrate using an epitaxial CVD process. The fabrication method disclosed in this invention uses a commercially available HPHT diamond substrate instead of natural diamond, combined with mature CVD epitaxial technology, offering advantages such as high product consistency, stable performance, controllable cost, and no need for an external power supply, making it suitable for mass production.
