Abstract
The effects of treatment with ammonium sulfide ((NH4)(2)S-x) solution on the electronic properties of InN surfaces have been investigated with high resolution x-ray photoemission spectroscopy. The valence band, In 3d, and N 1s x-ray photoemission spectra show that the surface Fermi level decreases by approximately 0.15 eV with (NH4)(2)S-x-treatment. This corresponds to a reduction of the downward band bending, with the surface sheet charge density decreasing by 30%. (C) 2009 American Institute of Physics. [doi:10.1063/1.3263725]
