Scientist (f/m/d) of Advanced In-System X-Ray Photoelectron Spectroscopy during the MBE Growth of Oxide Heterostructures on Semiconductors - Berlin

• QM 2025/3 In the Institute IFOX at HZB, we work on functional oxide thin films and nanostructures combined with semiconductors for energy-efficient information technology. We focus on material synthesis, detailed structural characterization using advanced methods, and on device properties for neuromorphic computing applications. You will work in the framework of the ERC Advanced Grant LUCIOLE (Layering, Understanding, Controlling, Integrating Ferroelectric Polar textures on Silicon). You will investigate the different steps of the growth of ferroelectric oxides such as BaTiO3 (and other compositions) on Si, Ge and SiGe substrates. Thanks to an XPS tool connected to the MBE cluster, the growth (including the very first steps of surface passivation) will be studied “in-system”, without air break. The information gained will allow engineering the interfaces with the substrate and between layers in superlattices. The postdoctoral scientist will work closely with the scientists performing the molecular beam epitaxy.
