Direct Imaging of Carbon-Covered and Clean Gold (110) Surfaces
Abstract
Results are presented on the atomic structure of gold (110) surfaces obtained by high-resolution electron microscopy. When covered by carbon, the 1×1 surface without surface relaxations is stable. Without carbon, a rough 2×1 reconstruction occurs with the missing-row structure, a 20%+/-5% outer-atom expansion and a 10% occupancy of atoms displaced outwards by 40%+/-20% down the channels. Local regions of 1×1 surface also exhibit a 10%+/-5% expansion of the outermost atoms.
