Our Research Topics

The group Advanced Thin Film Technology (ATFT) is focused mainly on the development of novel materials and material combinations by modern thin film deposition methods for applications in oxide electronics. We have developed several state-of-the-art and beyond-state-of-art thin film systems: a dedicated and world-wide unique system for ADvanced Oxide Molecular Beam Epitaxy (ADOMBE), a standard oxide MBE, several Pulsed Laser Deposition (PLD) and rf-magnetron sputter chambers. We strive to belong to the world-wide leading groups in oxide thin film technology.

From the viewpoint of materials, we focus on complex functional oxides. The functions we have in mind are (high-temperature) superconductivity, magnetic and ferroelectric properties as well as electrical (magneto-)conductivity. Characterization methods include dedicated thin film diffractometry, Superconducting QUantum Interference Device (SQUID), magnetoconductivity between 300 mK and 400 K in up to 17 T, and high-resolution electron microscopy. We investigate the fundamental materials properties, the effect of multilayer and hybrid systems, interfaces, and novel thin film matter and their functionality in integrated devices such as a tunneling magneto resitance (TMR) junction or a microwave varactor.
