Frenkel-Kontorova Model of Vacancy-Line Interactions on Ga/Si(112)

Abstract

We develop an exactly solvable microscopic model for analyzing the strain-mediated interaction of vacancy lines in a pseudomorphic adsorbate system. The model is applied to Ga/Si(112) by extracting values for the microscopic parameters from total-energy calculations. The results, which are in good agreement with experimental observations, reveal an unexpectedly complex interplay between compressive and tensile strain within the mixed Ga-Si surface layer.
