Note:
Validation Wafer:Considering convenience of usage, PAM-XIAMEN offer 2″ Sapphire Validation wafer for below 2″ size Freestanding GaN Substrate
Application of GaN Substrate
Solid State Lighting:GaN devices are used as ultra high brightness light emitting diodes (LEDs), TVs, automobiles, and general lighting
DVD Storage: Blue laser diodes
Power Device: GaN devices are used as various components in high-power and high-frequency power electronics like cellular base stations, satellites, power amplifiers, and inverters/converters for electric vehicles (EV) and hybrid electric vehicles (HEV). GaN’s low sensitivity to ionizing radiation (like other group III nitrides) makes it a suitable material for spaceborne applications such as solar cell arrays for satellites and high-power, high-frequency devices for communication, weather, and surveillance satellites
Ideal for III-Nitrides re-growth
Wireless Base Stations: RF power transistors
Wireless Broadband Access: high frequency MMICs,RF-Circuits MMICs
Pressure Sensors:MEMS
Heat Sensors: Pyro-electric detectors
Power Conditioning: Mixed signal GaN/Si Integration
Automotive Electronics: High temperature electronics
Power Transmission Lines: High voltage electronics
Frame Sensors: UV detectors
Solar Cells:GaN’s wide band gap covers the solar spectrum from 0.65 eV to 3.4 eV (which is practically the entire solar spectrum), making indium gallium nitride
(InGaN) alloys perfect for creating solar cell material. Because of this advantage, InGaN solar cells grown on GaN substrates are poised to become one of the most important new applications and growth market for GaN substrate wafers.
Ideal for HEMTs, FETs
