Pseudomorphism, the epitaxial growth of metastable phases, is reviewed. Emphasis is given to recent developments in the qrowth and investigation of α-Sn films on InSb and CdTe since this is a case where there is a very large strain energy barrier to the metastable to stable phase transformation. As a result, pseudomorphic growth of α-Sn can be sustained to film thicknesses of ∼1 μm.
Progress towards stabilization of direct gap group IV semiconductors is discussed and possible applications of pseudomorphism considered.
