Self-assembly, structure and electronic properties of a quasiperiodic lead monolayer

J. Ledieu, L. Leung, L. H. Wearing +4

A quasiperiodic Pb monolayer has been formed on the five-fold surface of the Al-Pd-Mn quasicrystal. Growth of the monolayer proceeds via self-assembly of an interconnected network…
