The Pentagon holds a strategic stockpile for germanium but currently has no inventory reserves for gallium, a spokesperson said on Thursday, after China announced export restrictions on the two ...
Gallium arsenide (GaAs) is a III-V direct band gap semiconductor with a zinc blende crystal structure. Gallium arsenide is used in the manufacture of devices such as microwave frequency integrated circuits , monolithic microwave integrated circuits , infrared light-emitting diodes , laser diodes , solar cells and optical windows.
The winning entry paid homage to the gallium arsenide on which the company was founded. *Tri, from the Greek for “a prefix meaning three, thrice, threefold”, and quint, from the Latin for “a set or sequence of five” literally means 3-5. 3-5 refers to the location of the elements gallium and arsenic on the periodic table.
Alta Devices was a US-based specialty gallium arsenide (GaAs) PV manufacturer, which claimed to have achieved a solar cell conversion efficiency record of 29.1%, as certified by Germany's Fraunhofer ISE CalLab. [1] [2] [3] The company has ceased operations. [1] [4]
Gallium arsenide antimonide, also known as gallium antimonide arsenide or GaAsSb (Ga As (1-x) Sb x), is a ternary III-V semiconductor compound; x indicates the fractions of arsenic and antimony in the alloy. GaAsSb refers generally to any composition of the alloy. It is an alloy of gallium arsenide (GaAs) and gallium antimonide (GaSb).
Following are responses from some companies to the announcement of curbs from Aug. 1 on Chinese gallium and germanium exports. * A spokesperson for the Semiconductor Equipment Association of Japan ...
China on Tuesday banned exports to the United States of the critical minerals gallium, germanium and antimony that have widespread military applications, escalating trade tensions the day after ...
On September 12, 2013, Oclaro, Inc. announced the sale of their Gallium-Arsenide (GaAs) laser diode business in Zurich to II-VI Incorporated (now Coherent) for $115M. As part of the agreement, II-VI purchased the Oclaro Zurich, Switzerland company, which includes its GaAs fabrication facility, and also the corresponding high-power laser diodes ...
