Atom-by-Atom Substitution of Transition Metals in GaAs and Visualization of Hole-Mediated Interactions
… interactions. In this thesis, we present a novel atom-by-atom substitution technique with the scanning tunnelling microscope (STM) to controllably incorporate transition metal dopants into GaAs. We compare the electronic states of isolated single acceptors in an identical configuration - Ga sites …

Atom-by-Atom Substitution of Transition Metals in Gallium Arsenide and Visualization of Hole-Mediated Interactions
We also present the first controlled atomic scale study of the interactions between isolated Mn impurities mediated by electronic states in GaAs. High-resolution STM measurements provide visualization of the GaAs electronic states that participate in Mn-Mn interactions. We quantify the interaction …
