Marios Hadjimichael

Profile

I joined Warwick as an Assistant Professor in January of 2024. Prior to coming to Warwick, I was a postdoctoral research assistant at the University of Geneva. I received my PhD from University College London in 2018, and my MSci and BA from the University of Cambridge in 2014.

Research Interests

I am interested in the properties of perovskite oxide systems and how they can be tuned using heterostructure engineering and strain. Some of my current research directions include the study of intrinsic electronic and structural properties at the domain walls of ferroelectrics, and strain or strain-gradient engineering of complex oxide systems that exhibit phenomena such as metal-to-insulator transitions and superconductivity.

To fabricate oxide thin films and multilayers I use off-axis radiofrequency magnetron sputtering and pulsed laser deposition. For their characterisation I use a range of complementary techniques including x-ray diffraction, impedance spectroscopy, low-temperature electronic transport, piezoresponse and atomic force microscopy, among others. Additionally, I take advantage of the advanced capabilities of large-scale facilities and conduct experiments at the Paul Scherrer Institut (Switzerland), Diamond Light Source (United Kingdom), and the European Synchrotron Radiation Facility (France) on a regular basis.

You can find more information about my research on my Google Scholar and ORCID pages.
