    We present a complex study of rare earth elements implanted GaN layers grown by low pressure metalorganic vapor phase epitaxy on c-plane sapphire substrates. Gd, Dy, La and Lu ions were implanted with energies of 200 key and doses ranging from 5 x 10(13) to 4 x 10(17) atoms.cm(-2). The chemical composition and concentration profiles of ion-implanted layers were studied by secondary ion mass spectrometry and Rutherford back scattering. The structural properties of the layers were characterized by Rutherford back scattering/channeling and X-ray diffraction reciprocal space mapping.
