Q: The epitaxial wafer on pss substrate is attractive to me, so I want to know the overall efficiency it can deliver. Could you please tell me an efficiency number (lm/w or cd/A or EQE) of the device based on a structure similar to [...]
Q:Do you have the optical characterization data for this InGaN wafer? We want to know want wavelength it emits when excited optically. A PL spectrum would be perfect. Also, is the InGaN grown on any buffer layer? What is the uniformity of the Indium [...]
Q:We need thickness,Semi-insulating SiC substrate, but your standard thickness is different, can you offer? A: Sure, we can offer unregular thickness, it is no problem.
Q:For 4” pss wafer, the light comes out from the p-GaN side not from sapphire, so I can’t do flip chip packaging. Also I don’t know whether laser liftoff is possible for pss wafer. Is it possible you can share any image of the etched surface of [...]
Q:Do you have LED wafers that can be used for fabrication of various research oriented structures? If yes, is your wafer unfabricated ? A: Yes, we can offer LED wafers unfabricated without contact, however we also can offer COW(chip on wafer).
Q:The ideal waverlength for us is 465 nm, can you offer?. A:It is no problem, but you should know the wavelength should be a range, what we will offer you 465+/-2nm.
