Germanium is a semiconductor
neither, germanium is a semiconductor
glass is an insulator, germanium is a metalloid.
conductor
those material having conductivity between insulator and good conductor are known as semiconductors for example germanium and silicon.
A semiconductor is a substance or material that conducts electricity better than an insulator but not as well as a conductor. Examples of semiconductors include silicon and germanium.
PVC plastic would be the best insulator.
A geranium is a flower, and not a semiconductor. The element Germanium, however, is a semiconductor, which means it has an electrical conductivity somewhere between that of a metal and an insulator.
It is not, silicon is. It is not possible to make ICs commercially using germanium (mostly because its oxide is crumbly and water soluble unlike silicon's oxide which is a stable and insoluble insulator, which means germanium ICs must be wired by hand under a microscope which is too costly for production). This means that germanium is limited to usage in discrete components (transistors & diodes) only. Some work is being done using silicon-germanium alloy for ICs, but it is not in the market yet.
A substance as germanium or silicon whose electrical conductivity is intermediate between that of a metal and an insulator; its conductivity increases with temperature and in the presence of impurities. :) Hope that helped;)
Yes Every metal is a conductor because of the free electrons (Except Silicon and Germanium; They are semi-metals) Yes, steel is a conductor
Germanium compounds are toxic.
