dc.description.abstract | The change in the surface band bandings of GaN films with crystal polarity and strain was investigated using synchrotron radiation photoemission spectroscopy. The Ga-face GaN sample showed larger surface band bending than the N-face one by 1.4 eV due to spontaneous polarization-induced sheet charges at the surface, resulting in a higher Schottky barrier height of a Pt contact. For both n-type and p-type GaN, the shift of the surface Fermi level with longitudinal tensile strain (similar to4 x 10(-3)) is negligible, while that with compressive strain (similar to3 x 10(-3)) is significant. This could be attributable to combined effects of piezoelectric polarization-induced sheet charges and the change of bandgap energy with the strains near the surface region.
