electron-photon avalanche
1Single-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… …
2Avalanche-Photodiode — Avalanche Photodioden bzw. Lawinenphotodioden (englisch avalanche photodiode, APD), sind hochempfindliche und schnelle Photodioden. Sie nutzen den inneren photoelektrischen Effekt zur Ladungsträgererzeugung und den Lawinendurchbruch… …
3Avalanche 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) …
4Photon — This article is about the elementary particle of light. For other uses, see Photon (disambiguation). Photon Photons emitted in a coherent beam from a laser Composition Elementary particle …

6Electron — For other uses, see Electron (disambiguation). Electron Experiments with a Crookes tube first demonstrated the particle nature of electrons. In this illustration, the profile of the cross shaped target is projected against the tube face at right… …
7Electron avalanche — An electron avalanche is a process in which a number of free electrons in a medium (usually a gas) are subjected to strong acceleration by an electric field, ionizing the medium s atoms by collision (called impact ionization), thereby forming new …
8Electron multiplier — Continuous dynode electron multiplier An electron multiplier is a vacuum tube structure that multiplies incident charges.[1] In a process called secondary emission, a single electron can, when bombarded on secondary emissive material, induce… …
9Electron-multiplying CCD — An electron multiplying CCD (EMCCD, also known as an L3Vision CCD, L3CCD or Impactron CCD) is a charge coupled device in which a gain register is placed between the shift register and the output amplifier. The gain register is split up into a… …
