The conventional coaxial germanium detector is often referred to as Pure Ge, HPGe, Intrinsic Ge, or Hyperpure Ge. Regardless of the superlative used, the detector is basically a cylinder of germanium with an n-type contact on the outer surface, and a p-type contact on the surface of an axial well.
Photodetectors among the most ubiquitous types of technology in use today. They range from simple devices that automatically open supermarket doors, to receivers on TV and VCR remote controls, to photodiodes in a fiberoptic connection, to the CCD in a video camera, to enormous arrays used by astronomers to detect radiation from the other side of the universe.

Jun 08, 2012· Another Pickard patent was the use of silicone as a detector, also patented in 1906. Following World War II the germanium diode was created, and began to replace the 's whisker detectors. The number of crystal radios being made were drastically reduced. Even today many people still collect 's whisker detectors for personal use.
State of the art large-volume germanium photon detectors comprise a volume of high purity germanium, an n+ hole blocking contact (lithium diffusion), a p+ electron blocking contact (boron implant) and an intercontact surface. The performance of an HPGe detector depends on the electrical characteristics of each of its constituent components.

This article is about ionizing radiation detectors. For information about semiconductor detectors in radio, see Detector (radio), Crystal detector, Semiconductor diodes, and Rectifier.. A semiconductor detector in ionizing radiation detection physics is a device that uses a semiconductor (usually silicon or germanium) to measure the effect of incident charged particles or photons.
Because germanium has relatively low band gap, these detectors must be cooled in order to reduce the thermal generation of charge carriers (thus reverse leakage current) to an acceptable level. Otherwise, leakage current induced noise destroys the energy resolution of the detector.
