A radiation detector made of boron(B)-doped/undoped diamond film stacking structure has been proposed, aiming at neutron detection using B-doped layer as a neutron-alpha converter. A prototype detector was fabricated using chemical vapor deposition (CVD)-grown polycrystalline diamond, and detections of both alpha particle and neutron were demonstrated. In addition, detection of alpha particle was characterized to investigate carrier transport and band model ...
