Abstract
The vibrational spectrum of hydrogen chemisorbed on Si(111)7×7 is studied with high-resolution infrared spectroscopy. A unique chemisorption site characterized by a dangling bond perpendicular to the surface is identified for the first time and assigned to a silicon atom at the bottom of a deep hole formed by long-range reconstruction.Keywords
