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 ...
Hundreds of regular patterns spontaneously emerge on a small germanium chip. A curiosity about tiny dots on a germanium wafer with metal films led to the discovery of intricate spiral patterns etched ...
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 ...
Benzer spent over a year tinkering with germanium until he discovered that mixing in trace elements of tin could produce rectifiers that were ten times more resistant than was standard.
Research into germanium for solar has re-emerged with several projects announced in the last two years. The cost of producing solar cells based on compounds of III-V element materials – named ...
Curiosity about a mistake that left tiny dots on a germanium wafer with evaporated metal films led to the discovery of beautiful spiral patterns etched on the surface of the semiconductor by a ...
A lab mistake led to self-forming spiral patterns on metal surfaces, revealing chemical-mechanical interactions.
Several textbooks—including one I coauthored—eliminated “metalloid” entirely and classified those elements as either metals or nonmetals, depending on their physical and chemical properties.
