A photoemission study of the diamond and the single crystal C<sub>60</sub>

Abstract

This report studied the elctronic structure of diamond (100) and diamond/metal interface and C60, using angle-resolved and core level photoemission. The C(100)-(2X1) surface electronic structure was studied using both core level and angle resolved valence band photoemission spectroscopy. The surface component of the C 1s core level spectrum agrees with theoretical existence of only symmetrical dimers. In the case of metal/diamond interfaces, core level and valence photoelectron spectroscopy and LEED studies WERE MADE OF B and Sb on diamond (100) and (111) surfaces. In the case of single-crystal C60, photoemission spectra show sharp molecular features, indicating that the molecular orbitals are relatively undisturbed in solid C60.
