| Summary: | 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$7
substrate.
Detailed descriptions of the structural and electronic properties of this
surface, obtained from density-functional calculations,
are presented and analyzed. A study of In clusters on this surface is performed, and compared
with recent experimental work on this system. The effect of surface strain as well as the issue
of the Si-Ge interface is addressed. Also, a preliminary investigation of some dynamical
aspects of an In atom on the 5$\times$5 surface is presented. === Thesis (Ph.D, Physics, Engineering Physics and Astronomy) -- Queen's University, 2007-10-26 14:14:48.513 === NSERC
