Prof. Dr. Martina Müller

The tunability of the oxygen content in complex oxide heterostructures has emerged as a key to deliberately set distinct functional phases and emerging electronic properties. I present routes on how to control oxygen-driven redox mechanisms in ultrathin ferro(i)magnetic and ferroelectric oxide films. I will address the growth and control of metastable EuO oxide phases, phase transitions of binary Fe oxides by oxygen migration as well as the role of interfacial oxide exchange in ferroelectric HfO2 based capacitors - uncovered by the unique capabilities of photoelectron spectroscopy and in particular using hard X-rays.
