Abstract

We report on the growth of unusual star shaped Bi islands and ordered arrays of nanorods on highly ordered pyrolitic graphite (HOPG) substrates. The rods and stars grow with {0 1 2}Bi||{0 0 1}HOPG and are preferentially aligned with the high symmetry directions of the substrate. As more Bi is deposited, the film undergoes a transition to the {0 0 1} orientation. These features are a result of a complex interplay between kinetics, thermodynamics, and the crystallography of the substrate and island material.
