By employing ab-initio total-energy and electronic-structure calculations based on the density-functional theory, we studied the effects of surface strain εs on the adsorption properties of a Au adatom on defective MgO(001) surfaces with surface oxygen vacancies (Fs centers). The formation energy of the Fs center on MgO(001) varied very slightly in the region of εs from −6% to −4% and monotonically...
