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
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
GaN Schottky diode project: We accept custom spec of Schottky diodes fabricated on the HVPE-grown, free-standing gallium nitride (GaN) layers of n- and p-types.
Both contacts (ohmic and Schottky) were deposited on the top surface using Al/Ti and Pd/Ti/Au.
Transmitance-GaN material-TEST REPORT
A test report is necessary to show the compliance between custom description and our final wafers data. We will test the wafer characerization by equipment before shipment, testing surface roughness by atomic force microscope, type by Roman spectra instrument, resistivity by non-contact resistivity testing equipment,micropipe density by polarizing microscope, orientation by X-ray Orientator etc. if the wafers meet the requirement, we will clean and pack them in 100 class clean room, if the wafers do not match the custom spec, we will take it off.
The transmittance of the wafer surface is the effectiveness of its transmission of radiative energy. Compared with the transmission coefficient, it is the fraction of the incident electromagnetic power transmitted through the sample, and the transmission coefficient is the ratio of the transmitted electric field to the incident electric field.
