Unusual charge states and lattice sites of Fe in Al x Ga1−x N:Mn

Unusual charge states and lattice sites of Fe in Al x Ga1−x N:Mn

Charge states and lattice sites of Fe ions in virgin and Mn-doped Al _x Ga _1− _x N samples were investigated using ^57 Fe emission Mössbauer spectroscopy following radioactive ^57 Mn ^+ ion implantation at ISOLDE, CERN. In the undoped Al _x Ga _1− _x N, Fe ^2+ on Al/Ga sites associated with nitroge...
