Uses: Gallium arsenide is capable of converting electricity directly into coherent light and is a key component of LEDs (light-emitting diodes) and some integrated circuits. Gallium is also used in semiconductors and solid-state devices, microwave equipment, low-melting alloys, mirrors, and high-temperature thermometers.
Gallium Nitride (GaN), being a wide-bandgap semiconductor, shows its advantage over the conventional semiconductors like Silicon and Gallium Arsenide for high temperature applications, especially in the temperature range from 300°C to 600°C. Development of stable ohmic contacts to GaN with low contact resistivity has been
The ohmic contacts of this invention have been fabricated to n-type Gallium Arsenide with an alloy of Aluminum Germanium which has a eutectic temperature of 424° C. with 53 weight percent Germanium. The lowest contact resistance of 1.4×10-6 ohm-cm 2 for the contact was measured with a transfer length transmission line structure.

Indium gallium arsenide (InGaAs) (alternatively gallium indium arsenide, GaInAs) is a ternary alloy (chemical compound) of indium arsenide (InAs) and gallium arsenide (GaAs). Indium and gallium are elements of the periodic table while arsenic is a element. Alloys made of these chemical groups are referred to as "III-V" compounds.
Gallium has three electrons in the outer shell, while arsenic lacks three. Gallium arsenide (GaAs) could be formed as an insulator by transferring three electrons from gallium to arsenic; however, this does not occur. Instead, the bonding is more covalent, and gallium arsenide is a…
