Abstract:
A device for detecting and measuring an electrical response due to a single charge carrier in a room-temperature semiconductor crystal, the device comprising:a high resistivity, semiconductor crystal, said crystal having first and second ends, said crystal having one surface or a plurality of surfaces disposed between said first and second ends, said surface or surfaces having a perimeter;a first electrode in electrical contact with said first end, said first electrode biased at a first electrical potential;a second electrode in electrical contact with said second end, said second electrode biased at a second electrical potential, said first potential greater than said second potential;at least one lateral contact disposed on or about said surface between said first and second ends, said lateral contact in electrical contact with said surface, said lateral contact is biased at a reference potential, said lateral contact and one of said electrodes further comprising a measurement pair.
