91Plasma diagnostics — are experimental techniques used to measure properties of a plasma such as temperature and density. Langmuir probe Measurements with electric probes, called Langmuir probes, are the oldest and most often used procedures for low temperature… …
92Electret — (formed of elektr from electricity and et from magnet ) is a dielectric material that has a quasi permanent electric charge or dipole polarisation. An electret generates internal and external electric fields, and is the electrostatic equivalent… …
93Radiosurgery — This article is about the medical procedure. For the album by American rock band New Found Glory, see Radiosurgery (album). Radiosurgery Intervention CLINAC: a model of steerable linear accelerator commonly used in radiosurgery …
94Debye sheath — The Debye sheath (also electrostatic sheath) is a layer in a plasma which has a greater density of positive ions, and hence an overall excess positive charge, that balances an opposite negative charge on the surface of a material with which it is …
95Metal-semiconductor junction — is a type of junction in which a metal comes in close contact with a semiconductor material. Similar to a p n junction, it has rectifying properties. History The rectification property of metal semiconductor contacts was discovered by Ferdinand… …
96Metal–semiconductor junction — In solid state physics, a metal–semiconductor junction is a type of junction in which a metal comes in close contact with a semiconductor material. Similar to a p n junction, it has rectifying properties. History The rectification property of… …
97Michael Francis Tompsett — is a British born physicist and former researcher at English Electric Valve Company, [1] who later moved to Bell Labs in America. He is best known as the inventor of Charge Coupled Device (CCD) Imagers used for imaging in devices such as digital… …
98Avalanche photodiode — Avalanche photodiodes (APDs) are photodetectors that can be regarded as the semiconductor analog to photomultipliers. By applying a high reverse bias voltage (typically 100 200 V in silicon), APDs show an internal current gain effect (around 100) …
99Thermionic converter — A thermionic converter consists of a hot electrode which thermionically emits electrons over a potential energy barrier to a cooler electrode, producing a useful electric power output. Caesium vapor is used to optimize the electrode work… …
100James M. Early — (1922 ndash;2004) was an American engineer, best known for his work on transistors and charge coupled device imagers. He is also known as Jim Early.The Early effect in bipolar junction transistors is named after Jim Early, who first characterized …
