• Ab initio Studies of Indium Clustering on the Ge(111)-5x5 Surface 

      Psiachos, Demetra (2007-10-29)
      This thesis reports an \textit{ab initio} study of the Ge(111)-5$\times$5 reconstruction, which forms on top of a Si(111)-7$\times$7 substrate. Detailed descriptions of the structural and electronic properties of ...
    • Silicon complexes in silicon doped calcium phosphate biomaterials 

      Gillespie, Paul Andrew (2008-01-03)
      The silicon complexes in silicon doped calcium phosphate bioceramics have been studied using $^{29}$Si magic angle spinning nuclear magnetic resonance spectroscopy. The replacement of phosphorus by silicon in these materials ...
    • Study of a non-interacting, nonuniform electron gas in two dimensions 

      Koivisto, Michael William (2007-11-08)
      The non-interacting, nonuniform electron gas exhibits simplifications in two dimensions, that are of particular interest in the application of density functional theory. The results of linear response theory for an attractive ...
