Semiconductor, английский
- A solid material characterized by comparatively high resistivities.
- A material whose resistivity lies between that of conductors and insulators, e.g., germanium and silicon. solid state devices such as transistors, diodes, photocells, and integrated circuits are manufactured from semiconductor materials.
- Полупроводник
- Any material that has a limited capacity for conducting an electric current. certain semiconductors, including silicon, gallium arsenide, copper indium diselenide, and cadmium telluride, are uniquely suited to the photovoltaic conversion process.
- A substance, commonly silicon or germanium, whose ability to conduct electricity falls between that of a conductor and that of a nonconductor (insulator). the term is used loosely to refer to electronic components made from semiconductor materials.
- An electronic material that can be an insulator under one condition and switch to a conductor under a different condition shear-thinning

Digital subscriber line (dsl), английский
A service that transmits digital signals to homes at speeds of hundreds of kilobits to tens of metabits per second over twisted-pair wires at higher frequencies than voice telephone signals. there are several variations.
Avalanche photodiode (apd), английский
A semiconductor photodetector with integral detection and amplification stages. electrons generated at a p/n junction are accelerated in a region where they free an avalanche of other electrons. apds can detect faint signals but require higher voltages than other semiconductor electronics.
