Title: Structure stability of epitaxial MgO-CaO solid-solution films: effect of diffusion

Abstract

The nonequilibrium epitaxial growth process of Mg{sub x}Ca{sub 1-x}O solid-solution films at 600 degree sign C is carefully investigated. No obvious phase separation is observed until annealing at 800 degree sign C despite a large miscibility gap. The solid-solution film is featured with disorder alloy as confirmed by transmission electron microscopy (TEM). Spinodal decomposition caused by uprising diffusion happens after short-time annealing which explicitly indicates the structure stability of the metastable solid-solution films does result from diffusion quenching.
