As U.S. President Donald Trump turns up the tariff heat on China, Beijing is targeting ever more of the United States' ...

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 ...

On April 4th, responding to Donald Trump’s tariffs, China restricted sales to America of seven rare earths. The move forces ...

During WWII, germanium was primarily used in point-contact diodes for radar pulse detection. After the war, from the 1950s to ...

China has banned exports of "dual-use items" related to gallium, germanium, antimony and super hard materials to the U.S.

[Doug’s] rendition uses the warm sounds of germanium transistors in a design that produces professional results. But if you need something a little bit less serious try the stomp-box.

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 ...

Voila: two gold contacts just a hair-width apart. The whole triangle was then held over a crystal of germanium on a spring, so that the contacts lightly touched the surface. The germanium itself ...

(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 ...

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 ...
