摘要
The surface properties of thin InN(0001) films grown by plasma assisted molecular beam epitaxy (PAMBE) were charecterised. Two stable surface reconstructions (a (2 x 2) and a (root 3 x root 3) R30 degrees) are identified which develop depending on the used preparation conditions. The structural, compositional and electronic surface properties were analysed insitu using reflection high energy electron diffraction (RHEED) and photoelectron spectroscopy (PFS). From the absence of surface contaminants as well as excess indium-it can be concluded that these superstructures are formed by single adatom layers.
