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:We want to know the refractive index of these SiC wafers? A:The refractive index is no=2.707, ne=2.755
Q: After MOCVD, do you anneal the wafer for p-GaN activation? A:Yes! We will anneal the wafer for p-GaN activation
Q: Regarding LED epi wafer,does the price include fabrication of p and n metal contacts? If not, can you fabricate p and n contacts plus SiO2 passivation based on my design? This can turn to a bigger project. A: Sorry, we can not offer fabrication of [...]
Q:For Si-doped GaN, what are the resistivity and mobility? A:Mobility:150-200Resistivity<0.05ohm.cm,
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:Can you offer SiC mono crystal material with high Thermal Conductivity > 490 W/mK, wafers with thickness: 300-1000um for semiconductor devices heat sinks manufacturing? A: Thermal Conductivity> 490 W/mK is theory value of SiC mono, however we tested some wafers, the thermal conductivity is below [...]
