Claims24
A radiation detector, comprising:
- a substrate made of semiconductor material;
- an electric field generating layer on a first face of the substrate;
- a first electrical contact on the first face of the substrate and next to the electric field generating layer;
- and
- a second electrical contact on the second face of the substrate and opposite to the electric field generating layer;
- wherein the electric field generating layer comprises:
- an inducing electrode;
- and
- an electrode insulator layer between the substrate and the inducing electrode.

A radiation detector, comprising:
- a substrate made of semiconductor material;
- an electric field generating layer on a first face of the substrate, the electric field generating layer comprising an inducing electrode and an electrode insulator layer between the substrate and the inducing electrode;
- a first electrical contact on the first face of the substrate and next to the electric field generating layer;
- and
- a second electrical contact on the second face of the substrate and opposite to the electric field generating layer,
- wherein the detector is configured to receive radiation through a radiation entrance window, the radiation entrance window comprising at least a portion of the electrode insulator layer;
- and
- wherein the detector is configured to, in response to the received radiation, cause a radiation induced current flow along a current flow path between the second electrical contact and the first electrical contact through a portion of the substrate.
