Solid-state impact-ionization multiplier — Solid State Impact Ionization Multipliers, or SIM, is a amplifier which amplify small input current signal into large current signal. The application includes Optical Receiver/Detector, Photomultiplier, and Image Sensing.The Advantage of the SIM… … Wikipedia
Electron ionization — [ toluene [http://webbook.nist.gov/cgi/cbook.cgi?Name=toluene Units=SI] ] Electron ionization (EI, formerly known as electron impact) is an ionization technique widely used in mass spectrometry, particularly for organic molecules. How it worksThe … Wikipedia
radiation — radiational, adj. /ray dee ay sheuhn/, n. 1. Physics. a. the process in which energy is emitted as particles or waves. b. the complete process in which energy is emitted by one body, transmitted through an intervening medium or space, and… … Universalium
Avalanche 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) … Wikipedia
Avalanche transistor — An Avalanche Transistor is a bipolar junction transistor designed for operation in the region of its collector current/collector to emitter voltage characteristics beyond the collector to emitter breakdown voltage, called avalanche breakdown… … Wikipedia
IMPATT diode — An IMPATT diode (IMPact ionization Avalanche Transit Time) is a form of high power diode used in high frequency electronics and microwave devices. They are typically made with silicon carbide owing to their high breakdown fields.They operate at… … Wikipedia
Fluorescent lamp — A fluorescent lamp or fluorescent tube is a gas discharge lamp that uses electricity to excite mercury vapor. The excited mercury atoms produce short wave ultraviolet light that then causes a phosphor to fluoresce, producing visible light.Unlike… … Wikipedia
Thermionic 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… … Wikipedia
Single-Photon Avalanche Diode — In optoelectronics the term Single Photon Avalanche Diode (SPAD)(also know as a Geiger mode APD or G APD) identifies a class of solid state photodetectors based on a reverse biased p n junction in which a photo generated carrier can trigger an… … Wikipedia
Avalanche breakdown — is a phenomenon that can occur in both insulating and semiconducting materials. It is a form of electric current multiplication that can allow very large currents to flow within materials which are otherwise good insulators. Explanation Avalanche … Wikipedia
Charge-coupled device — A specially developed CCD used for ultraviolet imaging in a wire bonded package. A charge coupled device (CCD) is a device for the movement of electrical charge, usually from within the device to an area where the charge can be manipulated, for… … Wikipedia
