Gallium nitride particles are semiconductor material particles with high hardness, high melting point, chemically stable, wide bandgap and high electron mobility, which can be used to manufacture high-power electronic devices and optoelectronic devices.<\/p>\n
Characteristics<\/p>\n
Appearance: generally yellow powder<\/p>\n
Density: Density 6.15g\/cm\u00b3.<\/p>\n
Hardness: very hard<\/p>\n
Melting point: The melting point is high, around 1227\u00b0C (2241\u00b0F). Decomposition temperature is 600\u00b0C (1110\u00b0F) and above.<\/p>\n
Bandgap width: Has a wide bandgap of about 3.4 eV. The wide bandwidth characteristics allow it to withstand higher voltages, provide better conductivity and stability in high power applications than traditional semiconductor materials, and can be used to make high power, high speed optoelectronic devices.<\/p>\n
Electron mobility: Higher electron mobility means that electrons move faster through the material and are able to complete the same operation in a shorter period of time, giving Gallium Nitride-based devices a faster response time to meet the needs of high-frequency, high-speed electronics.<\/p>\n
Thermal conductivity: high thermal conductivity, about 65.6 W\/m-K, can effectively conduct the heat generated in the working process of the device, reduce the temperature of the device, improve the reliability and stability of the device, and is conducive to working in high temperature environments.<\/p>\n
