Spatial Structure of an Individual Mn Acceptor in GaAs
Spatial Structure of an Individual Mn Acceptor in GaAs
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 …
