Radiation detector using diamond

摘要

The present invention relates to a radiation detector which includes a radiation detector using diamond, including: a radiation-detection layer (2) consisting of diamond, and a radiation-detector element having at least two electrodes (1, 1') intended to apply a voltage to the radiation-detection layer. The radiation-detection layer (2) is a highly oriented diamond film constructed by vapour-phase synthesis, 50% or more of the surface area of the diamond film being constituted by diamond [100] or [111] crystalline faces, and the differences { DELTA alpha , DELTA beta , DELTA gamma } existing between two sets of Euler angles { alpha , beta , gamma }, expressing the crystalline orientations of the adjacent [100] or [111] crystalline faces, simultaneously satisfy the relationships ¦ DELTA alpha ¦
