Q:Do you sell SiC wafers that are not (0001) plane? For example, (11-20)?
A:We can offer a-plane, but the size would be smaller,and should require quantity, do you have size requirement?

The InGaAsP material epitaxially grown on the InP substrate is an important material for the fabrication of optoelectronic and microwave devices. The emission wavelength of InGaAsP / InP laser structure covers 1.0-1.7μm, covering two low-loss windows of 1.3μm and 1.55μm for silica fiber communication. [...]
Q: SiC wafer reclaim, can you gurantee surface roughness<=0.3nm? A: Sure, no problem
Q:We want to know the refractive index of these SiC wafers? A:The refractive index is no=2.707, ne=2.755
Q: What is the minimum batch size for blue LED wafers on 4 inch sapphire (patterned sapphire)? A:5pcs is ok, but the price would be higher.
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:For pss wafer, the light comes out from the p-GaN side not from sapphire, so I can’t do flipchip packaging. Also I don’t know whether laser liftoff is possible for pss wafer. A:LED light is sourcing from mqw light, emitting in all directions, p-GaN is [...]
