摘要：
In this study, a radiation detector made of polycrystalline diamond was characterized by neutron , alpha particle. The detector consisted of a boron (B)-doped/undoped stacked structure, where the alpha particles were irradiated from the B-doped layer side. Radiation signals obtained by the multichannel analyzer were compared , bias dependence was investigated. Results indicate that the formation of the B-doped layer modifies band structure at B-doped/undoped interface, which improving signal hole collection.
