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 ...
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 ...
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 ...
Germanium detector history Since the 1960s, one constant in this ongoing pursuit of elusive subatomic knowledge has been the chemical element germanium. Situated in the carbon column of the ...
UCLA doctoral student Yilin Wong noticed that some tiny dots had appeared on one of her samples, which had been accidentally ...
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 ...
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 ...
China has presented itself as a neutral party and mediator since Putin launched the full-scale invasion three years ago.
(SiGe) A semiconductor material made from silicon and germanium. Germanium is very similar to silicon, but when one layer is grown on top of the other to form the base of the transistor ...
The United States relies heavily on other countries, particularly China, for essential metals used in technology, and this dependence makes the US vulnerable to export restrictions in trade disputes.
During WWII, germanium was primarily used in point-contact diodes for radar pulse detection. After the war, from the 1950s to the early 1970s, germanium's development as a semiconductor in ...
