ABSTRACT
V defects were observed in the ZnO films epitaxially grown on the ZnS-buffered Si. Although the defects were located on the surface, strong near-bandedge emission confined to the {1011} facets of V defects was observed at room temperature. The near-bandedge emission spreads out over the whole film centering at V defects at 30 K. The detailed optical characterization shows that activation of excitonic absorption is responsible for this unique optical behavior. © 2004 American Institute of Physics.

    We present evidence that it is the presence or absence of atomic terraces with a specific crystallographic orientation on the (102) Al2O3 surface that promotes growth of single-crystal (001) CeO2 films over polycrystalline (111) CeO2 films. The CeO2 film nucleates so that the [010] and [100]...
