Beschreibung
Zusammenfassung:A sensing element of an infrared detector including a first absorber configured to form a first set of minority carriers upon receipt of an infrared flux, a collector, a first barrier disposed between the first absorber and the collector, a second absorber configured to form a second set of minority carriers upon receipt of the infrared flux, and a second barrier disposed between the second absorber and the collector. In response to a voltage being applied to the collector, the first and second set of minority carriers are collected at the collector.
