Abstract
A structure of semiconductor radiation detector element having a p-n junction comprises a substrate layer including a radiation absorbing layer having a silicon equivalent thickness not smaller than 140 .mu.m and located adjacent to a depletion layer formed at the p-n junction. With the simplified structure, both the detection sensitivity and the energy compensating performance are enhanced significantly.
