We present a combined experimental and theoretical investigation of the early carbonization stages of the Si(111)-(7x7) surface upon acetylene exposure. Scanning tunneling microscopy images reveal the formation of a (root3xroot3)R30degrees reconstruction. Ab initio calculations allow us to characterize this reconstruction as a carbon-rich silicon phase due to subsurface incorporation of C atoms.

Abstract

We present a combined experimental and theoretical investigation of the early carbonization stages of the Si(111)-(7x7) surface upon acetylene exposure. Scanning tunneling microscopy images reveal the formation of a (root3xroot3)R30degrees reconstruction. Ab initio calculations allow us to characterize this reconstruction as a carbon-rich silicon phase due to subsurface incorporation of C atoms.
