摘要：

Magnesium-doped GaN grown by organometallic vapor phase epitaxy has been investigated by multitransmission infrared spectroscopy with the wave vector not along the c axis. This allows searching for local vibrational modes of complexes aligned along the c axis that cannot be seen by "normal" optical configuration. This technique, combined with polarized light, allows the precise determination of the geometry of the complexes. It has been found that the stable "magnesium-hydrogen" complex is not aligned along the c axis. The structure of this complex, including the angle between the electric dipole induced by the local mode and the c axis, has been determined. No other hydrogen-related complex aligned along the c axis has been detected.
