Growth of silicene on Ag(111) studied with low energy electron microscopy

Acun, Adil (2013) Growth of silicene on Ag(111) studied with low energy electron microscopy.

Abstract:The discovery of graphene and its properties is of big importance in the realm of science. Graphene exhibits exotic physical properties like the integer quantum Hall e�ect, the Klein paradox and a linear dispersion relation. The fact that silicon has similar properties as carbon has motivated the growth and study of a graphene-like material called silicene. To date only scanning tunneling microscopy (STM), atomic force microscopy (AFM), low energy electron di�raction (LEED) and angle-resolved photoemission spectroscopy (ARPES) experiments have been performed on silicene on Ag(111). Real-time imaging of changes in surface topography through surface di�usion, growth and phase transitions were not performed yet. Here, low energy electron microscopy (LEEM) has been used as a technique to study changes in surface topography. We �nd that a phase transition from silicene to sp3 hybridized silicon inhibits the growth of a second silicene layer. Furthermore, we conclude that it is not possible to cover a Ag(111) surface entirely with silicene.
