Neuromorphic Phototransistor with Biochemical Reconfigurability
ACS NanoNeuromorphic transistors with biochemical perception and reconfigurability are crucial for seamless human-robot interaction. However, existing hardware is limited by solid-state operation with electronic charge dynamics. Here, we present such a neuromorphic organic photoelectrochemical transistor (OPECT), in which two different biomolecules can be ...

Freestanding diamond films phototransistor
Surface and Coatings Technology, 2013Abstract High quality freestanding diamond (FSD) films with smooth nucleation surfaces were grown by microwave plasma chemical vapor deposition (MPCVD) method. A p-type hydrogenated surface conductivity of FSD film was obtained by using hydrogen plasma treatment.

GaN/InGaN avalanche phototransistors
Applied Physics Express, 2015We report on III–nitride (III–N) avalanche phototransistor (APT) action by illuminating ultraviolet (UV) photons onto a GaN/InGaN npn heterojunction bipolar transistor in an open-base configuration. A high responsivity of >1 A/W was measured for the device operating at a collector-to-emitter voltage (VCE) of 68 A/W at VCE = 95 V.

Unipolar Darlington Infrared Phototransistor
Japanese Journal of Applied Physics, 1997A novel unipolar infrared photodetector – the Darlington infrared phototransistor (DIPT) – is proposed and evaluated. The DIPT is the integration of a quantum-well infrared photodetector, utilizing the electron intersubband transitions, and a hot-electron transistor. The operation principle of the DIPT is considered.

A phototransistor galvanometer relay
Journal of Scientific Instruments, 1962On-off operation of a microswitch is attained with angular excursions of the in-built galvanometer light beam of about 3', which with a typical 10 ohm `portable' galvanometer corresponds to a sensitivity of about 0.005 μA. The optical system permits up to 30° forward over-travel of the light beam, so that the positioning of mechanical coil stops is not

Infrared Hot-Electron Phototransistor
Japanese Journal of Applied Physics, 1994A hot-electron phototransistor (HEPT) is proposed and discussed. The HEPT utilizes the intraband absorption of radiation in the base. This two-terminal device can operate as a photodetector for the infrared region of spectrum. Photoelectric performances of the HEPT are evaluated using an analytical model.
