Germanium

Germanium forms various compounds, including germanium dioxide (GeO2), germanium tetrachloride (GeCl4), and germanium tetrafluoride (GeF4). These compounds are commonly used in the production of semiconductor materials and optical fibers.

detector diodes in RADAR sets

The energy band gap for germanium is around 0.67 electron volts (eV) at room temperature. This makes germanium a semiconductor with properties in between those of conductors and insulators.

none

electrons or holes depending on doping, as in any semiconductor.

The permeability value of germanium is approximately 1.2 x 10^-5 H/m (henries per meter) at room temperature. This value may vary slightly depending on the purity and crystalline structure of the germanium sample.

Yes, germanium can be doped to exhibit p-type semiconductor behavior by introducing acceptor impurities such as boron. This leads to an excess of positively charged "holes" in the material, allowing it to conduct electricity in a manner characteristic of p-type semiconductors.

Germanium was discovered in Germany in 1886 by Clemens Winkler, a German chemist.

Germanium (Ge) is an chemical element, with atomic number 32. It can form a number of alloys, notably a silicon-germanium alloy, an important semiconductor with utility in high speed integrated circuitry in electronics.

To test germanium water, you can use a pH meter to measure the acidity level, a TDS meter to measure total dissolved solids, and a germanium testing kit to verify the presence and concentration of germanium in the water. Follow the instructions provided with these testing tools for accurate results.

It is used in guitar amps and fiber optics.

This varies inversely with the amount of impurities.

Only in certain types of electronics devices and you won't see it directly as contact with the water in air destroys its electronic properties, so germanium devices are hermetically sealed in either glass or metal.
