<title>Epitaxial oxide thin films: the new frontier</title>

The last decade has set the stage for the emergence of epitaxial metal-oxide films as one of the leading Optoelectronic material system of the future. This scenario was primarily stimulated by the advent of high temperature superconductors, a multi-component oxide, but more recently the resurgence of interest in doped oxide thin films has led to renewed interest in epitaxial oxide films in which a number of functionalities of importance to Optoelectronics have been seen. In this article we will make a brief sketch of the status of this technology.
