Nanoscale oxide heterostructures have been in the focus of cutting edge scientific and technological research. Reactive MBE and Laser MBE are two effective techniques in the growth of oxide thin films and heterostructures with controls to the atomic level. In my lab at Temple University, Laser MBE from separate oxide targets, e.g., growing SrTiO₃ films from SrO and TiO₂ targets and LaAlO₃ films from LaO and Al₂O₃ targets, has been recently developed to fabricate nanoscale oxide thin films and heterostructures with stoichiometry and crystallinity equal to those achieved by Reactive MBE. Having demonstrated the capability of precise controls of growth at the atomic layer level and film stoichiometry of Laser MBE from separate oxide targets, I will present two ongoing research projects to use this technique to fabricate designer oxide heterostructures. One would lead to artificial multiferroics materials, and the other would result in cuprate-like layered materials with possible high temperature superconductivity.

Xiaoxing Xi is the Laura H. Carnell Professor of Physics at Temple University. Prior to joining Temple in 2009, he was a Professor of Physics and Materials Science and Engineering at the Pennsylvania State University. He received his PhD degree in physics from Peking University and Institute of Physics, Chinese Academy of Science, in 1987. After several years of research at the Karlsruhe Nuclear Research Center, Germany, Bell Communication Research/Rutgers University, and University of Maryland, he joined the faculty of the Department of Physics at Penn State in 1995. He was a recipient of the NSF CAREER Award and a Chang Jiang Scholar at Tsinghua University, China. His research focuses on the materials physics relating to metal-oxide and boride thin films. He has published over 300 papers in refereed journals, book chapters, and conference proceedings, and holds three patents in the area of thin films of high Tc superconductors and magnesium diboride.
