Metallic ErSb Nanoparticles on a GaSb Surface
A.C. Gossard

Semimetallic ErSb nanoparticles were grown epitaxially on a GaSb surface by molecular beam epitaxy. The size and density of the metal nanoparticles can be controlled by the growth technique. The particles can also be overgrown and embedded in a semiconductor film. Narayanamurti will use BEEM to characterize the films and Kaxiras will do calculations to understand their structural and electronic properties.
