Please consider attending the following: MATERIALS ENGINEERING SEMINAR "Strain Turning and Property Enhancement for Functional Oxides" By Xingyao Gao Purdue MSE Ph.D. Preliminary Exam Advisor: Professor Haiyan Wang ABSTRACT Functional oxides are recognized as potential next-generation electronic materials due to their wide variety of properties, including high-temperature superconductivity, ferroelectricity, colossal magnetoresistance, multiferroism. Functional oxides can be widely used in energy storage, dielectrics, ferroelectrics, superconductors, magnetic, spintronic devices and catalysts. In last two decades, tremendous progress of the thin film growth techniques such as pulsed laser deposition (PLD), magnetron sputtering, spin coating and molecular beam epitaxy (MBE) has been made. With the development of these techniques, precise control of the film growth can be achieved. Strain tuning is one of the most promising methods that can help to enhance the properties of the thin films. According to the origin of the strain, there are three approaches on strain tuning: substrate induced strain, multilayer induced strain and vertically aligned nanocomposite (VAN) induced strain. In this seminar, a brief introduction of each strain tuning approach will be given. Examples will be illustrated on how these strain tuning approaches could enhance the ferroelectricity, multiferroism and magnetoresistance of functional oxides.
