Abstract

The optical and structural properties of Mn-implanted GaN films have been investigated. The films studied were grown by metal organic chemical vapor deposition (MOCVD), with Mn implanted in 150 KeV, which can offer many distinguished advantages compared with other doping methods. A new energy band with a minimum at 2.9 eV in the reflectance spectra has been observed. The yellow band emission was greatly decreased according to the result of photoluminescence. The structure analysis revealed that the Mn doped sample has good crystal quality as the pure GaN after annealed. And further discussions on the role of Mn in GaN: Mn films have been presented.
