Abstract

Nucleation and growth kinetics of dimer-adatom--stacking-fault (DAS) structures on laser-quenched Si(111) surfaces have been investigated by measuring the time evolution of DAS domain size distribution at $320--440\ifmmode^\circ\else\textdegree\fi{}\mathrm{C}$ with a scanning tunneling microscope (STM). The time evolution of the distribution suggests two different kinetics of DAS reconstruction. At a very early stage (immediately after laser irradiation), the surface contains many voids and formation of DAS structures is quite rapid. In the next stage (after the disappearance of the voids), the DAS domains develop at constant nucleation and growth rates in a measurable time scale. The temperature dependence of nucleation and growth rates is discussed based on a typical theory of the two-dimensional structural phase transition.
