- 1. Phys. Rev. B 69, 115210 (2004) , “Optical and magnetic properties of Mn in bulk GaN”, A. Wolos, M. Palczewska, M. Zajac, J. Gosk, M. Kaminska, A. Twardowski, M. Bockowski, I. Grzegory, S. PorowskiWe report results of electron paramagnetic resonance, magnetization, and optical absorption studies of bulk GaN crystals doped with Mn and, for some samples, codoped with Mg acceptor. The experiments performed show that the charge state of the Mn ion in GaN depends on the Fermi level position in the... (Read more)
- 2. J. Appl. Phys. 93, 9697-9702 (2003) , “Growth and characterization of GaN:Mn epitaxial films”, T. Graf, M. Gjukic, M. Hermann, M. S. Brandt, M. Stutzmann, L. Görgens, J. B. Philipp, O. AmbacherThe oxidation states of Mn in epitaxial GaN films grown by plasma induced molecular beam epitaxy were investigated by electron spin resonance (ESR), elastic recoil detection, superconducting quantum interference device magnetization, and photothermal deflection spectroscopy measurements. Comparison... (Read more)
- 3. Phys. Rev. B 63, 233202 (2001) , “Tetrahedral Mni4 Cluster in Silicon”, J. Wedekind, H. Vollmer, R. Labusch.Mni40 clusters were investigated by electron paramagnetic resonance in silicon specimens with initial doping concentrations between 1.5×1015?P cm-3 and 5×1016?B cm-3. In n-type samples and in intrinsic samples, we obtained the EPR... (Read more)
- 4. Phys. Rev. B 61, 1918 (2000) , “EPR investigation of manganese clusters in silicon”, J. Martin, J. Wedekind, H. Vollmer, and R. LabuschManganese centers were investigated in silicon specimens with initial doping concentrations between 1.5×1015 P cm-3 and 6×1015 B cm-3. All known Mn centers could be observed but the cluster Mni3Mni was missing in highly-boron-doped... (Read more)
