Gallium Nitride

Gallium Nitride Powder is a white or slightly yellow crystalline inorganic semiconductor powder with broad bandwidth, high electron mobility and high breakdown electric field, which has a wide range of applications in many fields such as power electronics and optoelectronics.

Characteristics

Appearance: usually present dark gray or white, slightly yellow powder.

Density: Density 6.1g/cm³.

Hardness: high hardness

Melting point: melting point is about 1700℃.

Stability: chemically stable, at room temperature, insoluble in water, dilute acid and ethanol, resistant to wet corrosion. However, it will decompose under the action of hot concentrated acid and alkali, and this characteristic can be utilized to detect defects in Gallium Nitride crystals.

Oxidation properties: When heated in air, it will slowly oxidize to produce oxides. It is unstable in high temperature hydrogen chloride gas or hydrogen, and more stable under nitrogen.

Bandwidth: The bandwidth is 3.4 eV, which is a wide bandwidth semiconductor material. The wide bandwidth characteristic makes Gallium Nitride able to withstand higher voltages and electric field strengths, and has important applications in high power and high frequency electronic devices.

Electron mobility: The high mobility of electrons in Gallium Nitride means that the electrons are able to move quickly through the material, resulting in devices with faster switching speeds and higher operating frequencies.
