Abstract

The effective use of ErSb semimetallic nanoparticles embedded within a semiconducting GaSb matrix, grown by molecular beam epitaxy, to manipulate the electronic andoptical properties of the composite material for a variety of applications is demonstrated. The resistivity, optical absorption, and photocarrier lifetimes, are all found to be greatly influenced by the size and density of the ErSb particles. The particle size and density can be controlled by growth parameters resulting in a versatile and highly tunable composite material.
