Last month, Beijing banned the export of gallium, germanium, and antimony, key metals used in chipmaking, to the U.S. after the U.S. Commerce Department subjected more Chinese companies to export ...
Gallium arsenide is an important semiconductor material for high-cost, high-efficiency solar cells and is used for single-crystalline thin-film solar cells and for multi-junction solar cells. [35] The first known operational use of GaAs solar cells in space was for the Venera 3 mission, launched in 1965.
China's export controls on some gallium and germanium products take effect on Tuesday with traders braced for a drop in international supply in August and September while exporters sort out newly ...
Like silicon, gallium, bismuth, antimony, and water, germanium is one of the few substances that expands as it solidifies (i.e. freezes) from the molten state. [ 36 ] Germanium is a semiconductor having an indirect bandgap , as is crystalline silicon.
