Typical analyses of low- and mid-temperature solders focuses on improvements to important metrics such as shock resistance and component resilience.
The only germanium found in other diodes (and rectifiers and transistors) would be those made between the 1950's and 1970's. After that, high-purity silicon took its place in those applications, because of the much lower cost compared to the relatively rare germanium. Now, in the Shottky diodes it's not merely the primary electrode metal that's ...

The metal/germanium (Ge) photodetectors have attracted much attention for their potential applications in on-chip optoelectronics. One critical issue is the relatively large dark current due to the limited Schottky potential barrier height of the metal/germanium junction, which is mainly caused by the small bandgap of Ge and the …

China said on Monday it will impose export restrictions from Aug. 1 on some gallium and germanium products, metals used in computer chips and other products, to protect national security interests.
Germanium as a Semiconductor Material. Moreover, germanium's intrinsic attributes enable diffusion – a process where atoms navigate from areas teeming with concentration to zones sparsely populated within the semiconductor. The mystery deepens when dopant materials are integrated into the matrix of germanium semiconductors.
The semiconductors inside computer chips are made from raw materials like silicon, germanium, phosphorus, boron, indium phosphide and gallium. Without these substances, the world as we know it would look very different — there would be no smartphones or laptops, no rockets or electric cars. Here is a closer look at the most …
Germanium forms stable oxidation states of +2 and +4, the compounds of the latter being more stable and numerous. The two most important compounds of germanium are the dioxide (GeO 2) and the tetrachloride (GeCl 4).Germanates, formed by heating the dioxide with basic oxides, include zinc germanate (Zn 2 GeO 4), used as a …
