| 摘要 |
A semiconductor radiation detector and a radiation detection equipment capable of suitably preventing the deterioration of the detection characteristics are disclosed. The semiconductor radiation detector 1 includes a semiconductor crystal 11a formed of at least one of CdTe, CdZnTe, GaAs and TlBr held between the electrodes of a cathode C and an anode A. At least one of the electrodes is a stack structure including a plurality of metals. The first layer is formed of Pt or Au, and the second layer is formed of a metal lower in hardness than Pt or Au, as the case may be, of the first layer. The second layer of In, for example, is formed by the electroless plating method. Also, a metal may be further stacked on the second layer.
