Growth of Oxide Thin Films on Different Natures of Substrates for Various Electronic and Medical Applications

Transition metal oxides often having a perovskite structure form a wide and technologically important class of compounds. In these systems, ferroelectric, ferromagnetic, ferroelastic, or even orbital and charge orderings can develop and eventually coexist. These orderings can be tuned by external electric, magnetic, or stress field, and the cross-couplings between them enable important multifunctional properties, such as piezoelectricity, or magneto-elasticity. In spite of the large number of observations and promise of epitaxial oxide thin films, most of the investigations have been focused on films on low-index commercially-available single-crystal substrates, which have limited the scope of the study, and the applications. Here, we will present how oxide thins films can be grown on different types of substrates including polycrystalline substrates, and glass templates. Examples will given to show different applications that can be utilized for medical or electronics.
