Abstract
A novel device-the quantum-dot infrared phototransistor (QDIP)-is prop osed and considered theoretically. The QDIP utilizes intersubband elec tron transitions from the bound states. The dark current and sensitivi ty are calculated using a proposed analytical model of the QDIP. It is shown that the QDIP can exhibit low dark current, high photoelectric gain and sensitivity surpassing the characteristics of other intersubb and photodetectors.
