Abstract : This report briefly summarizes work completed on the above grant during the time period of December 1, 1989 to November 30, 1995. The grant has concentrated on Scanning Tunneling Microscopy/Spectroscopy (STM/STS) studies of atomic-scale structure and morphology in semiconductors. Earlier work on this grant, which was initiated in 1990, was extended the past three years (partially through the addition of AASERT funding) to include efforts to develop microcathodoluminescence (micro CL), scanning tunneling luminescence (STL), and near-field scanning optical microscopy (NSOM) for investigating local optical properties of surfaces and small structures and relating these to morphological properties and structural defects.
