Description:

One area of importance in semiconductor development are the kinetics of monomers (single Si atoms) on the surface of a crystal, namely, the sticking and residence times of monomers at steps and islands. In this work, the atomic-scale behavior of the binding of silicon monomers at steps and islands on the Si(001) surface is measured directly using variable-temperature scanning tunneling microscopy (STM).
