Radiation detector

A semiconductor radiation detector system, the semiconductor radiation detector system, comprising:

• a semiconductor material having a first surface and a second surface, the first surface being opposite from the second surface, the semiconductor material including at least one metal component, the semiconductor material effective to absorb radiation and induce a current pulse in response thereto;
• a readout circuit;
• and
• at least one first electrode contact attached to the first surface and at least one second electrode contact attached to the second surface, wherein the first electrode contact and the second electrode contact are conductively connected to the readout circuit and the first electrode contact includes a metal doped oxide where the metal doped oxide includes an oxide of the metal component of the semiconductor material.

A method of making a radiation detector, the method comprising:

• receiving a semiconductor material having a first surface and a second surface, the first surface being opposite from the second surface, the semiconductor material including at least one metal component, the semiconductor material effective to absorb radiation and induce a current pulse in response thereto;
• depositing a metal doped oxide on the first surface of the semiconductor material, wherein the oxide includes a component element of the semiconductor material;
• and
• depositing the metal doped oxide on the second surface of the semiconductor material.
