Arsenide

BEIJING (Reuters) – U.S. semiconductor wafer maker AXT Inc said its Chinese subsidiary Beijing Tongmei had received initial export permits for shipping gallium arsenide and germanium substrates – compounds key to chipmaking – to certain customers.

The researchers suspected that cadmium arsenide's three-dimensional electronic structure would help attain high efficiency in this conversion.

About 66% of semiconductor gallium is used in the U.S. in integrated circuits (mostly gallium arsenide), such as the manufacture of ultra-high speed logic chips and MESFETs for low-noise microwave preamplifiers in cell phones.

Aluminium gallium arsenide (AlGaAs) is used in high-power infrared laser diodes.

Gallium arsenide (GaAs) and gallium nitride (GaN) used in electronic components represented about 98% of the gallium consumption in the United States in 2007.

Gallium arsenide is used in some integrated circuits (ICs) and photovoltaic devices.

In order to provide the tenfold increase in performance that he always demanded of his newest machines, Cray decided that the machine would have to be built using gallium arsenide semiconductors.

Mono-crystal silicon wafers (or for special applications, silicon on sapphire or gallium arsenide wafers) are used as the substrate.

Na 2 Po has the antifluorite structure, the polonides of Ca, Ba, Hg, Pb and lanthanides form a NaCl lattice, BePo and CdPo have the wurtzite and MgPo the nickel arsenide structure.

Night vision devices Photons hitting a thin film of alkali metal or semiconductor material such as gallium arsenide in an image intensifier tube cause the ejection of photoelectrons due to the photoelectric effect.

Second to silicon, gallium arsenide (GaAs) is the second most popular semiconductor used.

Some materials such as Gallium Arsenide have an effective electron affinity that is below the level of the conduction band.

The development of gallium arsenide as a direct band gap semiconductor in the 1960s ushered in the most important stage in the applications of gallium.

The first single-chip gallium arsenide radar module was developed.
