Topics in solid phase epitaxy: Strain, structure and geometry

The effects of some experimental parameters on the solid-phase crystallization of amorphous films on single crystals, a process known as Solid Phase Epitaxy (SPE), are examined. Results from a large community of researchers concerning SPE of alloys and compounds, strained films, films in constrained geometries and films with unusual amorphous/crystal interfaces are reviewed. Our present understanding of mechanisms involved in SPE is given, and the implications of the wide range of experimental results are discussed.
