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:For Si-doped GaN, what are the resistivity and mobility? A:Mobility:150-200Resistivity<0.05ohm.cm,
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: Regarding your red LED epiwafers, what about the top layer or cap layer on the epiwafer structure? A: As before we have p+GaAs(several nanometers only) in the top layer, however these two years, due to technology innovation, and all foundry remove this layer [...]
Q: Can you offer some SiC(0001) wafers with low but intentionnal misorientation in the 1° to 2° range? A: We can offer misorientation in low degree, no problem.
Q:Do these 2” PSS LED wafers have the same epi-stack as the 4” PSS? If not, please send me the diagram with thicknesses. Wavelength can be same: central 455nm A: the 2″ detail layer thickness and structure is same as 4″, no any difference. Wavelength:455nm+/-5nm [...]
