Fine structure and real space analysis of neutral acceptor states in GaAs

“…It is well established that exchange interaction in single {Mn + hole} complex is relatively small. Some authors estimate the value ε which is half the splitting between ground and first excited levels to be of the order of 5 meV [43][44][45], some report even smaller values about 1-2 meV [46][47][48]. There are also papers [32] about the determination of the parameter β N 0 used to describe p-d exchange in GaMnAs materials, but the link to the 2-spin exchange (ε) depends on the wavefunction of the acceptor state on the − A core.…”
