Germanium is a chemical element; it has symbol Ge and atomic number 32. It is lustrous, hard-brittle, grayish-white and similar in appearance to silicon. It is a metalloid (more rarely considered a metal) in the carbon group that is chemically similar to its group neighbors silicon and tin. Like silicon, germanium naturally reacts and forms ...
Silicon–germanium. SiGe (/ ˈsɪɡiː / or / ˈsaɪdʒiː /), or silicon–germanium, is an alloy with any molar ratio of silicon and germanium, i.e. with a molecular formula of the form Si 1−x Ge x. It is commonly used as a semiconductor material in integrated circuits (ICs) for heterojunction bipolar transistors or as a strain -inducing ...
"The (Defense) Department is proactively taking steps using Defense Production Act Title III authorities to increase domestic mining and processing of critical materials for the microelectronics ...
Semiconductor detector. 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. Semiconductor detectors find broad application for radiation protection, gamma and X-ray spectrometry, and as particle ...
Spot prices of germanium ingot have jumped nearly a third in the past month to an all-time high of 13,250 yuan ($1,826.48) a kilogram (kg) on Wednesday, data from information pr
Following are responses from some companies to the announcement of curbs from Aug. 1 on Chinese gallium and germanium exports. * A spokesperson for the Semiconductor Equipment Association of Japan ...
Such properties have made SiGe thermoelectrics convenient for power generation in space. The multifoil cold stack assembly, composed of molybdenum, tungsten, stainless steel, copper, and alumina materials, provides the insulation between the electrical and thermal currents of the system.
Bottom right: completed solar wafers. In electronics, a wafer (also called a slice or substrate) [ 1 ] is a thin slice of semiconductor, such as a crystalline silicon (c-Si, silicium), used for the fabrication of integrated circuits and, in photovoltaics, to manufacture solar cells. The wafer serves as the substrate for microelectronic devices ...
