摘要: A radiation detector includes a photodiode composed of an .alpha.-SiC substrate of a first conductivity type, a first .alpha.-SiC layer of the first conductivity type epitaxially formed on the .alpha.-SiC substrate, a second .alpha.-SiC layer of a second conductivity type having higher carriers concentration than the first .alpha.-SiC layer and epitaxially formed on the first .alpha.-SiC layer, a first electrode formed on the .alpha.-SiC substrate in ohmic contact, and a second electrode formed on the second .alpha.-SiC layer in ohmic contact; and a phosphor layer disposed on the photodiode to emit ultraviolet-rays by exposure of radiations.
