Description
  • A nondestructive approach to determine the wurtzite GaN crystal polarity based on X-ray photoelectron diffraction is proposed. The approach, utilizing the ratio of photoemitted electron currents excited by a standard laboratory X-ray source from the N 1s level in the (10 -10) plane at polar angles of 20 and 25 , is tested on GaN crystals. The photoelectron intensity ratio I20/I25 is larger or smaller than unity for GaN(0001) or GaN(000 -1), respectively. The approach can be used for polarity determination of other binary wurtzite crystals. The atom with the smaller electron scattering cross-section should be used as the emitter.
