Abstract
We report a complete far-infrared investigation of shallow level centres in GaN. Transitions between the ground and excited states of shallow donors h ave been observed by means of transmission and far-infrared photoconductivi ty measurements - the latter for two configurations of the magnetic field r elative to the crystal axis. The hitherto unobtainable high quality of the spectra allows, for the first time, a comparison with a theoretical model o f shallow donors in a crystal with a wurtzite structure.
