- 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, 042503 (2006) , “Evidence for magnetism due to oxygen vacancies in Fe-doped HfO2 thin films”, Nguyen Hoa Hong, Nathalie Poirot, and Joe SakaiFe-doped HfO2 thin films are room temperature ferromagnetic. In comparison with results of the undoped HfO2 films, it seems that the Fe doping is not the main cause for the ferromagnetism but only acts as a catalyst. Experimental results of oxygen annealing and vacuum heat... (Read more)
- 3. 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)

Dózsa, N. G. Galkin, D. L. Goroshko, V. O. Polyarnyi, and E. A. ChusovitinSchottky contacts on p-type silicon, with embedded arrays of β-FeSi2 nanocrystallites, were studied by current-voltage (I-V), deep level transient spectroscopy (DLTS), and low-frequency noise measurements. Forward I-V characteristics on logarithmic... (Read more)
- 5. J. Appl. Phys. 100, 024510 (2006) , “Influence of iron contamination on the performances of single-crystalline silicon solar cells: Computed and experimental results”, S. Dubois, O. Palais, M. Pasquinelli, S. Martinuzzi, C. Jaussaud, and N. RondelIn this paper, the impact of iron contamination on the conversion efficiency of single-crystalline p-type silicon solar cells is investigated by means of the combination of numerical simulations and experimental data, taking into account the more recent results about the properties of iron in...

- 6. J. Appl. Phys. 100, 023539 (2006) , “Mechanisms for the activation of ion-implanted Fe in InP”, T. Cesca, A. Verna, G. Mattei, A. Gasparotto, B. Fraboni, G. Impellizzeri, and F. PrioloIn this paper we present structural and electrical investigations on high temperature Fe-implanted InP. The aim of the work is to relate the lattice position of the implanted atoms after annealing treatments (from 300 to 600 °C) with their electrical activation as compensating deep traps and...

- 7. Mater. Sci. Eng. B 126, 222-225 (2006) , “Magnetic properties of a new spintronic material—GaN:Fe”, H. Przybylińska, A. Wolos, M. Kiecana, M. Sawicki, T. Dietl, H. Malissa, C. Simbrunner, M. Wegscheider, H. Sitter, K. Rumpf, P. Granitzer, H. Krenn and W. JantschWe report on metal-organic chemical vapour deposition growth of GaN:Fe and its characterization by means of high-resolution X-ray diffraction, secondary ion mass spectroscopy, electron spin resonance, and magnetization measurements. Electron spin resonance studies demonstrate the existence of Fe in... (Read more)
- 8. Phys. Rev. B 74, 235207 (2006) , “Vacancy-enhanced ferromagnetism in Fe-doped rutile TiO2”, Jun Chen, Paul Rulis, Lizhi Ouyang, S. Satpathy, and W. Y. ChingBased on a series of supercell density functional calculations of Fe-doped TiO2 both with and without O vacancy (VO), we show that VO plays an important role in determining the magnetic properties of the dilute magnetic semiconductors (DMS). Without... (Read more)
- 9. Phys. Rev. B 74, 195204 (2006) , “Interaction of iron with the local environment in SiGe alloys investigated with Laplace transform deep level spectroscopy”, Vl. Kolkovsky, A. Mesli, L. Dobaczewski, N. V. Abrosimov, Z. R. ytkiewicz, and A. R. PeakerLaplace transform deep level transient spectroscopy (LDLTS) is used to investigate the alloy effects on iron related deep centers in Si1−xGex. A clear buildup of alloy disorder as a function of the germanium content has been observed for the isolated... (Read more)

Cottenier, C. M. Comrie, and A. VantommeWe present a study on the interpretation of conversion electron Mössbauer spectra reflecting an infinite number of sites, in casu Mössbauer spectroscopy on Fe1−xSi layers on Si, synthesized by pulsed laser annealing. These spectra display a broad... (Read more)
