The following is an interaction between UniversityWafer, Inc and a researcher.
I have already purchased item number 1306. Can you please tell me what is C to M-plane means? I am wondering to know the crystal orientation in this sapphire wafer.
Sapphire Wafer Item #1306 - 50.8mm 430um SSP C to M-plane by 0.2±0.1 deg off.
C to M-plane means: C-Plane(0001) off-axis towards to M-axis
Yes,crystal orientation in this sapphire wafer C-plane,small mis-cut angle @ 0.2deg,of which is a industrial standard C-plane sapphire.
One more question, I have irradiated this wafer and I want to study crystal orientation after irradiation then compare the result with non-irradiated wafer. Did you have any data for X-Ray Diffraction (XRD) related study for this non-irradiated sapphire wafer? Thanks you so much.
