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 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 ...
The germanium itself sat on a metal plate attached to a voltage source. This contraption was the very first semiconductor amplifier, because when a bit of current came through one of the gold ...

What Are Semiconductors, and What Are They Made Of?A semiconductor is a material or device that only conducts electricity under certain conditions. Some elements in the periodic table, such as carbon, silicon, and germanium, are intrinsic ...
The approach, termed ‘germanium on nothing’, could enable ... The NREL estimates semiconductor substrates for cell growth represent around 30% of the cost of a III-V solar cell.
