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 [...]
Q:Our application will be making micro-pillar arrays based on the MQWs for high brightness LEDs and its wavelength tuning. So we do not really care the emission wavelength you provide but we will mind whether the process and emission wavelength would be consist between [...]
Q:Could you tell us also what type of 4-H polytype SiC sudstrate you are able to provide? A: Sure.
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.
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 atomic ratio for Si/C in SiC ? A:Atomic ratio for Si/C in SiC is 1:1
