Abstract

The interaction between nano-scale objects of different dimensionality, e.g. electrostatic Coulomb-coupled zero-dimensional quantum dots (QD’s) to two-dimensional (2D) systems, is both of fundamental interest and great relevance for the future of memory technology. GaSb/(Al)GaAs quantum dots provide strong hole-confinement, with potential to provide storage times of many years at room temperature [1].
