Term (Index) Definition
phototransistor  a bipolar transistor, typically heterojunction, in which collector-base junction is a p-i-n junction acting as photodetector.
photoelectric effect  energy of radiation is converted into electric current in the irradiated semiconductor; energy of radiation must be greater than semiconductor energy gap.
transistor  three-terminal semiconductor device in which input signal (voltage or current depending on the type of transistor) controls output current; the most important semiconductor device; performs switching and amplifying functions; early on replaced bulky and inefficient vacuum triode in electronic circuits; invention of transistor (Schockley, Brattain and Bardeen, 1947) triggered electronic revolution after the World Word II; can operate as a discrete device or a building cell of integrated circuits; numerous kinds of transistors can be distinguished based on their design and principles of operation; there are two types of transistors: unipolar (field-effect transistor, or FET) and bipolar.

Reference: See history of transistor
photodiode  two-terminal device with built-in potential barrier; typically p-n junction often in p-i-n version; its reverse current changes upon illumination with light featuring energy higher than semiconductor's energy gap.
