41Threshold voltage — The threshold voltage of a MOSFET is usually defined as the gate voltage where an inversion layer forms at the interface between the insulating layer (oxide) and the substrate (body) of the transistor. The creation of this layer is described next …
42radiation measurement — ▪ technology Introduction technique for detecting the intensity and characteristics of ionizing radiation, such as alpha, beta, and gamma rays or neutrons, for the purpose of measurement. The term ionizing radiation refers to those… …

44Acoustic impedance — The acoustic impedance Z (or sound impedance) is a frequency f dependent parameter and is very useful, for example, for describing the behaviour of musical wind instruments. Mathematically, it is the sound pressure p divided by the particle… …
45Dielectric spectroscopy — A dielectric permittivity spectrum over a wide range of frequencies. The real and imaginary parts of permittivity are shown, and various processes are depicted: ionic and dipolar relaxation, and atomic and electronic resonances at higher energies …
46Transformer design — This page deals primarily with the design of electrical transformers. For the definition, function, and history, see Transformer.In electrical engineering, practical transformer design requires knowledge of electrical principles, materials, and… …
47Superconducting Radio Frequency — (SRF) science and technology involves the application of electrical superconductors to radio frequency devices. The ultra low electrical loss of the superconductor yields RF resonators with extremely high quality factors, or Q . For example, it… …
48Cadmium telluride solar cell — Articleissues advert = October 2008 COI = October 2008 wikify = October 2008A cadmium telluride solar cell is a solar cell based on a cadmium telluride (CdTe) thin film, a semiconductor layer to absorb and convert sunlight into electricity… …
49Magnetosphere — A magnetosphere is formed when a stream of charged particles, such as the solar wind, interacts with and is deflected by the intrinsic magnetic field of a planet or similar body. Earth is surrounded by a magnetosphere, as are the other planets… …
50Skin effect — Skin depth redirects here. For the depth (layers) of biological/organic skin, see skin. Skin effect is the tendency of an alternating electric current (AC) to distribute itself within a conductor with the current density being largest near the… …
