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 ...

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 ...

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 ...

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 ...

China's commercial space sector is developing rapidly. Yunnan Germanium Co., Ltd. (002428.SZ) plans to invest nearly 300 million yuan in a germanium wafer construction project for space solar cells.

[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.

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.

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 ...
