Electroluminescence (el)
| Глоссарий терминов в нанотехнологиях |
The light produced by some materials — mainly semiconductors — when exposed to an electric field. in this process, the electric field excites electrons in the material, which then emit the excess energy in the form of photons. light-emitting diodes (leds) are the most well known example of el.

Electroluminescence, английский
- Luminescence arising from electrical influences
- The emission of light from a phosphor excited by electromagnetic energy.
Semiconductors, английский
The silicon-based integrated circuits that drive the operations and functioning of computers and most electronic devices.
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

Electron diffraction, английский
A surface science technique used to examine solids by firing a beam of electrons at a sample and observing the electron deflection from the sample’s atomic nuclei.
Electrochemical properties, английский
The characteristics of materials that occur when a) an electric current is passed through a material and produces chemical changes and b) when a chemical reaction is used to produce an electric current, as in a battery.
