- 1. Phys. Rev. B 75, 144404 (2007) , “Ferromagnetism in Fe-doped ZnO nanocrystals: Experiment and theory”, Debjani Karmakar, S. K. Mandal, R. M. Kadam, P. L. Paulose, A. K. Rajarajan, T. K. Nath, A. K. Das, I. Dasgupta, and G. P. DasFe-doped ZnO nanocrystals are successfully synthesized and structurally characterized by using x-ray diffraction and transmission electron microscopy. Magnetization measurements on the same system reveal a ferromagnetic to paramagnetic transition temperature above 450 K with a low-temperature... (Read more)
- 2. Appl. Phys. Lett. 89, 012508 (2006) , “Ferromagnetism in Fe-implanted a-plane ZnO films”, P. Wu, G. Saraf, Y. Lu, D. H. Hill, R. Gateau, L. Wielunski, R. A. Bartynski, D. A. Arena, J. Dvorak, A. Moodenbaugh, T. Siegrist, J. A. Raley, and Yung Kee YeoFe ions of dose 5×1016 cm2 were implanted at 200 keV into a-plane ZnO epitaxial films. The epitaxial quality of the postannealed samples was verified by x-ray diffraction -rocking curves and scans, whereas x-ray absorption spectroscopy identified the... (Read more)
- 3. Superlatt. Microstruct. 39, 247-256 (2006) , “Optical and morphological features of bulk and homoepitaxial ZnO”, R. Yakimova, G.R. Yazdi, N.T. Son, I. Ivanov, M. Syväjärvi, S. Sun, G. Tompa, A. Kuznetsov , B. SvenssonZnO substrate crystals from two different sources, and epitaxial layers have been studied by SEM, AFM, photoluminescence and EPR. Although fabricated by the same growth principle, i.e. the hydrothermal technique, the substrates differ in terms of purity and structural quality. In the PL spectra of... (Read more)
- 4. Solid State Commun. 8, 45-47 (1970) , “A note on the splitting of the ( →← -) line in the ESR spectrum of Fe3+ in ZnO”, I. D. Campbell , J. O. CopeIons of spin which occupy inequivalent cation sites in a wurtzite lattice show ESR line splitting. An analytical expression is derived which describes the dependence of the splitting of the ( →← -) line on crystal orientation. This expression provides a convenient method of deducing... (Read more)
