Abstract:
1. A detection apparatus comprising: a transistor disposed on a substrate; a conversion element disposed on the transistor and connected to the transistor; a capacitor connected in parallel with the conversion element to the transistor, the capacitor including, between the substrate and the conversion element, a first ohmic contact part connected to the conversion element, a semiconductor part connected to the first ohmic contact part, and an electrically conductive part disposed at a location opposite to the semiconductor part and the first ohmic contact part via an insulating layer; and a potential supplying unit configured to selectively supply a first electric potential to the electrically conductive part to accumulate charge carriers in the semiconductor part and a second electric potential to the electrically conductive part to deplete the semiconductor part, wherein the capacitor further includes an electrode layer disposed so as to oppose the electrically conductive part, and wherein the electrode layer is connected to a second ohmic contact part disposed so as to oppose the first ohmic contact part via the semiconductor part.
