Gallium nitride (apart from its optoelectronic applications) is a system particularly interesting from the point of view of surface physics research. Its surfaces may reconstruct in various ways depending on formation conditions (surface polarity, preparation method, and presence of impurities). Moreover, doping with transition metals may transform GaN into a ferromagnetic semiconductor. Annealing of Mn/GaN is considered as a technique suitable for fabrication of this material.
