Abstract
Room temperature adsorption of I-2 on the Ge(lll) surface is found to break the initial c(2 x 8) adatom reconstruction as iodine preferentia lly occupies the on top substrate site, breaks the backbonds between t he adatom and the substrate and thus removes the Ge adatoms. As this p rocess continues a c(2 x 4), and modifications thereof, reconstruction is formed consisting of chains of I-2 molecules bound in almost T-1 s ites with a I-I bond length of 3.6 Angstrom.
