Abstract
New angle-resolved photoemission measurements of the valence structure of Sn/Ge(111) were carried out, focusing on the (3×3) zone boundary. A gap opening was observed around the (3×3) zone boundary. A slight change in state occupancy due to defect doping led to large changes in electronic response, resulting in a Peierls-like (3×3) instability.
