Abstract

GaSb quantum dots embedded in GaAs-based device structures have exciting potential in a number of emerging electronic and optoelectronic applications. They are a type-II system whose band-structure provides strong confinement for heavy-holes and no confinement for electrons. Despite this type-II nature, excitons can still be bound to GaSb dots, with the Coulomb interaction dominating the physics of the electron’s binding.
