Germanium is a semiconductor in group IVA of the periodic table. It has an atomic number of 32, an atomic weight of 72.59, and a density of 5.32 Mg/m 3. Its melting temperature is 937.4 C. Germanium ...

One of the graduate students, Seymour Benzer, accidentally discovered that a crystal of germanium -- a semiconductor which was not well understood at the time -- could withstand higher voltage ...

Germanium is used in fiber optic systems and infrared optics, solar cells, and transistors. Antimony is a flame retardant in various products, a component in lead-acid batteries, and an ingredient ...

But they have a rich history, going back through the silicon era to germanium junction transistors, and thence to the original devices. if you’ve ever looked at the symbol for a transistor and ...

Amid the ongoing US-China chip war over the past years, the Chinese government has taken counter-measures, including export restrictions on critical materials such as gallium, germanium ...

(Bloomberg) -- Two obscure yet crucial metals, gallium and germanium, are the latest pawns in the escalating US-China trade war. On Dec. 3, China announced an export ban on both metals to the US ...

Many people giving talks had complained about the current germanium transistors -- they had a bad habit of not working at high temperatures. Silicon, since it's right above germanium on the ...
