    • Structural disorder induced in hydrogenated amorphous silicon by light soaking 

      Gibson, J. M.; Treacy, M. M. J.; Voyles, P. M.; Jin, H-C.; Abelson, J. R. (1998)
      We show, using variable coherence transmission electron microscopy, that light soaking of amorphous hydrogenated silicon thin films leads to structural changes. We speculate that the structural changes are associated with ...
    • Structural, optical, and magnetic characterization of monodisperse Fe-doped ZnO nanocrystals 

      Parra-Palomino, A.; Perales-Perez, O.; Singhal, R.; Tomar, M.; Hwang, Jinwoo; Voyles, P. M. (2008)
      The results on the synthesis and characterization of highly monodisperse Fe-doped ZnO nanocrystals are presented. Stable suspensions of these materials were produced in an ethanol solution at room temperature. To promote ...
    • Structure and physical properties of paracrystalline atomistic models of amorphous silicon 

      Voyles, P. M.; Zotov, N.; Nakhmanson, S. M.; Drabold, D. A.; Gibson, J. M.; Treacy, M. M. J.; Keblinski, P. (2001)
      We have examined the structure and physical properties of paracrystalline molecular dynamics models of amorphous silicon. Simulations from these models show qualitative agreement with the results of recent mesoscale ...
    • Tuning of magnetic properties in cobalt ferrite nanocrystals 

      Cedeno-Mattei, Y.; Perales-Perez, O.; Tomar, M. S.; Roman, F.; Voyles, P. M.; Stratton, W. G. (2008)
      Cobalt ferrite CoFe2O4 possesses excellent chemical stability, good mechanical hardness, and a large positive first order crystalline anisotropy constant, making it a promising candidate for magneto-optical recording ...
