Abstract:
The nonequilibrium epitaxial growth process of MgxCa1-xO solid-solution films at 600 degrees C is carefully investigated. No obvious phase separation is observed until annealing at 800 degrees 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.
