Germanium has the diamond cubic crystal structure shown, an fcc lattice with a basis of two germanium atoms, one at (0,0,0) and the other at (1/4, 1/4, 1/4) in units of the cube edge. It can also be ...

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 ...

G-ray’s original idea was to grow germanium crystals directly onto CMOS (complementary metal-oxide-semiconductor) processed silicon wafers. However, CMOS is ill-suited to the temperatures needed ...

Haynes put electrodes on both sides of a thin germanium crystal and took very sensitive measurements of the size and speed of the current. Electricity definitely flowed straight through the crystal.

ERPOC is the only U.S. manufacturer producing (growing) customer specific germanium and silicon crystals for use in military, aerospace and commercial markets. ITAR compliant, ISO certified, we supply ...

BANGKOK (AP) — China announced Tuesday it is banning exports to the United States of gallium, germanium, antimony and other key high-tech materials with potential military applications ...
