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 ...
Prices of germanium, a strategic metal key to chipmaking, hit a record high on Wednesday in top producer China, driven by speculation of possible state buying, industry sources said. China ...
Germanium-tin is an alloy of the elements germanium and tin, both located in group 14 of the periodic table. It is only thermodynamically stable under a small composition range. Despite this limitation, it has useful properties for band gap and strain engineering of silicon-integrated optoelectronic and microelectronic semiconductor devices.
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 ...
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 ...
The present and future of Wolfspeed, the fast-growing semiconductor chipmaker in Durham, are closely linked to China. The company, which produces semiconductors to power appliances like electric ...
A semiconductor is a material that is between the conductor and insulator in ability to conduct electical current. [1] In many cases their conducting properties may be altered in useful ways by introducing impurities ("doping") into the crystal structure. When two differently doped regions exist in the same crystal, a semiconductor junction is ...
A semiconductor device is an electronic component that relies on the electronic properties of a semiconductor material (primarily silicon, germanium, and gallium arsenide, as well as organic semiconductors) for its function. Its conductivity lies between conductors and insulators. Semiconductor devices have replaced vacuum tubes in most ...
