Abstract

Mg accepters in GaN epitaxial layers grown by metal-organic vapour-phase epitaxy were investigated by optically detected magnetic resonance (ODMR) spectroscopy. The magnetic resonances were detected on the magnetic circular dichroism (MCD) of the acceptor bound exciton ((MgX)-X-0) in the near bandgap region, and in the infrared spectral range on the MCD of the hole ionisation transition Mg-0 + hv --> Mg- + h(VB). The observed g-values of the Mg-0 accepters range for g(parallel to) from 2.102 to 2.065 and for g(perpendicular to) from 1.94 to 2.00, respectively. These variations depend on the Mg doping concentration. (C) 1999 Elsevier Science B.V. All rights reserved.
