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?

Q We actually want to check our reflectance (mirror type) measurement method on an LED structure on a PSS wafer. Would it be possible to get the same LED structure on both a PSS wafer and a single-side polished wafer so we can compare the two directly?

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.
