Q:We want to know the refractive index of these SiC wafers?
A:The refractive index is no=2.707, ne=2.755
Q:Dislocation density < 1E8 of GaN on sapphire from what kind of characterization? A:Considering edge dislocation and mixing dislocation and then abtained by XRD
Q:Our application will be making micro-pillar arrays based on the MQWs for high brightness LEDs and its wavelength tuning. So we do not really care the emission wavelength you provide but we will mind whether the process and emission wavelength would be consist between [...]
Q: For GaN on sapphire, could you please let us know which side is epi-ready? A: Ga-face,epi-ready and N face is connecting to sapphire.
Q: We need SiC bare wafer, mechanical grade, do you have? A: Sure, mechanical grade is just our dummy grade wafer.
Q:In your web site, the picture of the SiC wafer does not look like regular, transparent-light green color SiC wafer. Why is that? A: Good question, the picture in website is Polarized light image.In regular, it is green color or grey color.
Q:What atomic ratio for Si/C in SiC ? A:Atomic ratio for Si/C in SiC is 1:1
