Abstract

Photon detectors responding in UV to-IR including free carrier based homo- and hetero junction interfacial workfunction internal photoemission (HIWIP/HEIWIP) detectors, split-off band detectors, quantum dot infrared photodetectors (QDIPs), and colloidal quantum dot (CQD) detectors are discussed. HIWIP and HEIWIP detectors were focused to develop far-infrared (or terahertz) and dual-band detectors, while split-off detectors and QDIPs were considered for room temperature or TE-cooled operation. QDIPs have also shown multi-color characteristics with narrow response peaks. For ultraviolet/visible/near-infrared multi-band detection, CQD detectors have shown promising results at room temperature.
