Application of single crystal germanium

For the manufacture of semiconductor devices. P-type germanium is obtained by doping trivalent elements such as indium

How does germanium dioxide reduce to germanium

Germanium dioxide, the molecular formula of GeO2, is the dioxide of germanium with the same electronic formula as carbon dioxide. It is white powder or colorless crystal. There are two kinds of hexagonal crystal system (low temperature stability) which is

Infrared principle

All objects in nature, as long as its temperature is higher than absolute zero (- 273 ℃), can radiate electromagnetic waves.

Infrared thermal imaging refrigeration technology

Stirling refrigeration technology has a history of 50 years, and is widely used in military. The first is the integral structure, that is, the compression piston and the expansion piston are mechanically connected by a connecting rod. The integral structu

Distribution of germanium resources

Germanium is a typical rare dispersed element, which is about 7 parts per million in the earth's crust. Germanium has the chemical properties of lithophile

Germanium dioxide

Germanium dioxide is a kind of germanium dioxide with the same electronic formula as carbon dioxide. It is white powder or colorless crystal. There are two kinds of hexagonal system which is slightly soluble in water (stable at low temperature) and insolu
