Heteroepitaxial growth of Pt (001) films on SrTiO3 by pulsed laser deposition

New functional materials are being considered having in perspective an impo rtant role in the development of microsystems. In particular, in an experim ent of pulsed laser deposition (equipped with in situ reflection high-energ y diffraction of the growth surface) thin Pt epitaxial layers have been dep osited on SrTiO3 (0 0 1) substrates. It is shown that thin single-crystal l ayers of metallic Pt (0 0 1) can be heteroepitaxially grown on SrTiO3 (0 0 1). Furthermore complex SrTiO3 - Pt - SrTiO3 heteroepitaxial structures hav e been deposited. This result is of relevant importance for the growth of n ew functional materials consisting of heteroepitaxial structures involving both complex oxides and standard metals. These materials may reasonably ope n up new prospects in the field of microsystem technologies.
