RADIATION DETECTION ELEMENT USING OXIDE CRYSTAL AND METHOD OF MANUFACTURING OXIDE CRYSTAL

摘要

PROBLEM TO BE SOLVED: To provide a highly-sensitive radiation detection element having a small dark current by using a material having low toxicity and excellent environmental friendliness.SOLUTION: A radiation detection element of the present invention includes: a semiconductor layer comprising a crystal of a tin oxide; and detection means for detecting, as an electric signal, a charge that is generated in the semiconductor layer as the semiconductor layer receives irradiation with a radiation. The resistivity of the semiconductor layer is 10Ωcm or higher.
