Abstract
New ordered compounds have recently been observed to form pseudomorphically during epitaxial growth. These phases do not appear on the equilibrium bulk phase diagram. The paper first reviews the current knowledge of epitaxial strain layers. A linear stability analysis is presented of the competition among disordered phases strained by an epitaxial constraint and of the corresponding ordered epitaxial compounds. The case of volume misfit for mixed alkali halides is carried through in detail to reveal the delicate energy balance, the orientation dependences involved, and the effects of lattice anharmonicity on phase competition at the growth temperature.
