I am using SOI wafer for my research work. When i am doing XRD then i am getting major peak 69.58. I matched this with JCPDS Data base. That peak reported as Si peak.
Can any one explain it, why this peak not reported as Si
If I pass a laser light through 100, 110, 111 or polycrystal sheet, will scattering, diffraction happen or not? As when x-ray pass through different planes, it happens. Can anyone suggest the...
