The effect of gold nanoclusters on the growth and properties of homoepitaxial strontium titanate layers — •Sandra Christke1, Ralf Erlebach1, Frank Schmidl1, Jürgen Kräußlich2, Markus Rettenmayr3, and Paul Seidel1 — 1Friedrich-Schiller-University Jena, Institute of Solid State Physics, Helmholtzweg 5, 07743 Jena, Germany — 2Friedrich-Schiller-University Jena, Institute of Optics and Quantum Electronics, Max-Wien-Platz 1, 07743 Jena, Germany — 3Friedrich-Schiller-University Jena, Institute of Materials Science and Technology, Löbdergraben 32, 07743 Jena, Germany
We use pulsed layer deposition (PLD) to fabricate single crystal thin films and layer systems which can be epitaxially deposited. Here we present analysis regarding the growth of strontium titanate (STO) layers on single crystal STO substrates. The specific characteristic of these experiments is the deposition of the STO layer through PLD. Therefore, during the formation of the STO layer onto the substrate the initial gold layer is transformed into nanoclusters. We show the dependence of crystallographic and optical properties as a function of gold and STO layer thicknesses as well as surface parameters.
