摘要： The present disclosure provides a radiation detector, comprising: a semiconductor crystal for detecting radiation, the semiconductor crystal comprising a top surface, a bottom surface, and at least one side surface; at least one anode arranged on at least one of the top surface, the bottom surface, and the at least one side surface; and at least one cathode arranged on at least another one of the top surface, the bottom surface, and the at least one side surface, wherein the at least one anode each has a stripe shape, the at least one cathode each has a planar or curved shape, and the at least one cathode and the at least one anode extend in parallel with respect to each other to a length substantially equal to that of the anode. Such an electrode structure can improve energy resolution and detection efficiency of the radiation detector effectively.
