Structures and stability of nonpolar AlN(1\bar{1}00) and (11\bar{2}0) surfaces under hydrogen rich conditions are theoretically investigated by performing total-energy calculations within the density functional theory. The calculated surface energies demonstrate that several hydrogen incorporated structures are favorable depending on the chemical potentials of constituting elements. However, H atoms desorb and the relaxed ideal surfaces are stabilized even under the metal--organic vapor-phase expitaxy growth. These results suggest that the growth processes on AlN nonpolar surfaces are quite different from those of polar surfaces.
