Title:
RADIATION DETECTION ELEMENT, RADIATION DETECTOR, AND RADIATION DETECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/070737
Kind Code:
A1
Abstract:
Provided are a radiation detection element, a radiation detector, and a radiation detection device with which it is possible to increase a sensitive region. This radiation detection element comprises: a semiconductor part having an incident surface on which radiation is incident; a first electrode which is provided on a surface on the rear side of the incident surface, and into which charges, generated inside the semiconductor part by the incidence of radiation, flow; and a second electrode which is disposed on the incident surface and positioned on the rear side of the first electrode, and to which a voltage required for the inflow of the charges to the first electrode, wherein the radiation detection element includes a third electrode provided on the incident surface and disposed at a position surrounding the second electrode, the third electrode is electrically connected to the second electrode, and a voltage is applied across the second electrode and the third electrode such that the potential changes from the third electrode to the second electrode.
