Epitaxial Stabilization of Multifunctional Oxide, Oxynitride, and Telluride Thin Films using a Hybrid Pulsed Laser Deposition Technique — Pia Henning, Anna Tschesche, Shagun Thakur, Niklas Kohlrautz, Abhishek Sharma, Laura Pflügl, and •Jasnamol Palakkal — Institute of Materials Physics, Georg-August-University of Göttingen, Friedrich-Hund-Platz 1, 37077 Göttingen, Germany

Materials science uses state-of-the-art thin film techniques, such as pulsed laser deposition (PLD) and molecular beam epitaxy (MBE), to artificially fabricate complex materials [1]. Epitaxial films with controlled defects and orientation are practical for modifying functionalities. We developed a hybrid PLD system attaching molecular beam sources (for elements with high vapor pressure) to fabricate multifunctional oxide, oxynitride, and tellurides. Additionally, gases are provided through a microplasma source. This setup makes a wide range of cation and anion engineering possible in complex materials. In this presentation, we will address challenges in the growth of thin films and how modifications in the defects and structure influence functional properties by taking examples of La₂NiMnO₆ (ordered magnetism and electrocatalysis), Cr_xTe (ferromagnetism and magnetic anisotropy), and SrNbO₃ (optical transparency and metallic conduction). Moreover, we will discuss how such a hybrid deposition system can be utilized to grow high-entropy materials and stabilize doping beyond the solubility limit. [1] A.
