Q : 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 p and n metal contacts, also we can not fabricate p and n contacts plus SiO2 passivation.
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 [...]
Q:For Si-doped GaN, what are the resistivity and mobility? A:Mobility:150-200Resistivity<0.05ohm.cm,
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: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:What atomic ratio for Si/C in SiC ? A:Atomic ratio for Si/C in SiC is 1:1
Q:We are using 40×40 mil size and 45×45 mil size chips for 1W . And 45×22 or 38x22mil size for 0,5w . Eff. is min. 120lm/w , package form is 3535 ceramic no lens flat type, and 5050 smd flat type.Cct 6500k, cri min 70-75, [...]
