The intramolecular and electronic structure of C60 stabilized in monolayer films on a Cu(100) surface has been studied with low temperature scanning tunneling microscopy (STM) and spectroscopy. In contrast to other single crystal metal surfaces, C60 adopts four unique orientations on the Cu(100) surface due to a reconstruction of the underlying copper atoms. Spectroscopy and spatial imaging of molecular orbital resonances from LUMO to LUMO+3 for the four distinct adsorption geometries are presented. Shifts in the MO resonances indicate different degrees of electronic molecule-surface hybridization for the four geometries. Additionally, nanoscale modulation of the relative work function is observed across the film which correlates with the proposed atomic-scale electrode reconstruction. 2010-12-17 English text The Ohio State University / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=osu1291191115 http://rave.ohiolink.edu/etdc/view?acc_num=osu1291191115 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
