Abstract
Measurements of the nucleation rate of macrovacancies (''Lochkeim'' fo rmation) on Si(001) during high-temperature sublimation are presented. A theoretical description of macrovacancy nucleation on evaporating s urfaces is also given. The nucleation rate is shown to follow a non-Ar rhenius behavior as a function of temperature. The experiment is seen to compare favorably with the theory.
