The wave function of a hole bound to an individual Mn acceptor in GaAs is spatially mapped by scanning tunneling microscopy at room temperature and an anisotropic, crosslike shape is observed. The spatial structure is compared with that from an envelope-function, effective mass model and from a tight-binding model. This demonstrates that anisotropy arising from the cubic symmetry of the GaAs crystal produces the crosslike shape for the hole wave function. Thus the coupling between Mn dopants in…

TLDR
Calculations of the acceptor-state wavefunction in the presence of strain, within a tight-binding model and within an effective-mass model agree with the experimentally observed shape and can be explained on the basis of the observed local density of states for the single Mn spin.
