Abstract
The present invention provides radiation detectors with high detection sensitivity. The radiation detectors according to the present invention each include an Al2O3 substrate, a CaxCoO2 (where 0.15<x<0.55) thin film that is layered on the Al2O3 substrate and that has CoO2 planes that are aligned inclined to the surface of the Al2O3 substrate, a first electrode disposed on the CaxCoO2 thin film, and a second electrode disposed on the CaxCoO2 thin film in a position opposed to the first electrode in the direction in which the CoO2 planes are aligned inclined. The surface of the Al2O3 substrate is an n plane or an S plane.
