Is electron accumulation universal at InN polar surfaces?
Recent experiments indicate the universality of electron accumulation and downward
surface band bending at as-grown InN surfaces with polar or nonpolar orientations. Here,
we demonstrate the possibility to prepare flatband InN (000 1) surfaces. We have also
measured the surface stoichiometry of InN surfaces by using core-level photoelectron
spectroscopy. The flatband InN (000 1) surface is stoichiometric and free of In adlayer. It
implies that the removal of In adlayer at the InN (000 1) surface leads to the absence of …
