(11-22) Plane U-GaN Freestanding GaN Substrate
PAM-XIAMEN's GaN(Gallium Nitride) substrate is singlecry stal substrate with high quality, which is made with original HVPE method and wafer processing technology. They are high crystalline, good uniformity, and superior surface quality. GaN substrates are used for many kinds of applications, for white LED and LD(violet, blue and green), Furthermore development has progressed for power and high frequency electronic device applications.
GaN is a very hard (12±2 GPa, mechanically stable wide bandgap semiconductor material with high heat capacity and thermal conductivity. In its pure form it resists cracking and can be deposited in thin film on sapphire or silicon carbide, despite the mismatch in their lattice constants. GaN can be doped with silicon (Si) or with oxygen to n-type and with magnesium (Mg) to p-type. However, the Si and Mg atoms change the way the GaN crystals grow, introducing tensile stresses and making them brittle.Galliumnitride compounds also tend to have a high dislocation density, on the order of 108 to 1010 defects per square centimeter. The wide band-gap behavior of GaN is connected to specific changes in the electronic band structure, charge occupation and chemical bond regions
GaN technology is used in numerous high-power applications such as industrial, consumer and server power supplies, solar, AC drive and UPS inverters, and hybrid and electric cars. Furthermore, GaN is ideally suited for RF applications such as cellular base stations, radars and cable TV infrastructure in the networking, aerospace and defense sectors,thanks to its high breakdown strength, low noise figure and high linearity.
Surface Roughness-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.
Surface roughness is usually shortened to roughness and is a component of surface texture. It is quantified by the deviation of the normal vector direction of the real surface from its ideal form. If these deviations are large, the surface is rough; If they’re small, the surface is smooth. In surface measurement, roughness is generally considered to be the high frequency short-wave length component of measuring scale surface. In practice, however, it is often necessary to know the amplitude and frequency to ensure that the surface is suitable for a purpose.
Below is an example of surface roughness of GaN material:
