Abstract: Thin film technology has attained its prominence in recent years due to its very many important and diversified applications in modern time. Fabrication of high quality thin films depends on numerous factors. Epitaxy is the most significant film growth process. In the case of hetero-epitaxy, lattice matching is one of the crucial parameters needed to be considered. Strain would be induced as long as the difference in lattice constant exists. Some previous studies have shown that the strain layers resulted from lattice mismatch can be very interesting and useful. Indeed, significantly enhanced or even new properties have been observed in some strain layers. It is therefore a scientific and technological challenge to be able to prepared films with prescribed strain on them so as to produce tailor-made properties for certain applications. In this study, we have employed pulsed laser deposition to fabricate epitaxial films of tunable lattice constant, which could serve as useful templates for growth of controllable strain layers.
