Q: We would like to ask for below. (001) +/- 0.5o Orientation Semi Insulating, Undoped Resistivity ≤ 1 – 10 x 108 Ohm-cm3 EPD ≤ 5000 cm-2 1 Side Polished (Ra < 10Å), EPI Ready, Back Side Etched US Semi Standard Flats, No Laser [...]
Q: I am not sure whether practically LLO can be done on the PSS given it is not a flat surface A: “laser lift-off” actually is according to “NL layer” as below image. If the NL layer is GaN layer, when it is heating to constant high [...]
Q:In the test report of blue LED wafers,it shows Vf and IV (mcd). How is this mcd being measured without actually processing the wafer into devices? A:We use prober equipment and contact positive and negative pole, connect current, and then get the voltage and IV.
Q:What atomic ratio for Si/C in SiC ? A:Atomic ratio for Si/C in SiC is 1:1
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:For Si-doped GaN, what are the resistivity and mobility? A:Mobility:150-200Resistivity<0.05ohm.cm,
