Ge(001)-(2 1 0 3)-Pb <-> (2 1 0 6)-Pb: low-temperature two-dimensional phase transition

O. Bunk, M. M. Nielsen, J. H. Zeysing +7

The Ge(001)-(2 1 0 3)-Pb surface reconstruction with a lead coverage of 5/3 monolayer is on the borderline between the low-coverage covalently-bonded and high-coverage metallic lea…
