Abstract
We present results on the direct spatial mapping of the wave function of a hole bound to a Mn acceptor in GaAs. To investigate individual Mn dopants at the atomic scale in both ionized and neutral configurations, we used a room temperature cross-sectional scanning tunneling microscope. We found that in the neutral configuration manganese manifests itself as an anisotropic cross-like feature. We attribute this feature to a hole, weakly bound to the Mn ion forming the (Mn/sup 2+/3d/sup 5/+hole) complex
