will produce current-switched memristive devices from quantum materials and use coherent X-ray imaging to track the nanoscale dynamics of the switching under steady-state and pulse current excitation. The projects are closely linked through the materials classes, fabrication methods and imaging methods. Experiments will be carried out both in our one-of-a-kind ultrafast XUV imaging beamline at IMDEA and at large scale X-ray facilities worldwide. A solid background in optics, nanofabrication and/or condensed matter physics is desirable. This position is supported by an FPI fellowship from the Agencia Estatal de Investigacion of Spain.

We especially welcome applications from women and other under-represented groups in physics. Please include a CV and two references.

About the group: The Ultrafast Science of Quantum Materials group at IMDEA Nanoscience in Madrid, Spain studies light-driven phenomena in quantum materials, particularly phase transitions and the out-of-equilibrium phases using a variety of laboratory and facility-based experiments. Currently consisting of 9 members from 4 continents, we pride ourselves on a creative and welcome environment. Based in the north of Madrid at the Campus of International Excellence UAM+CSIC, IMDEA Nanoscience is dedicated to the exploration of nanoscience and the development of applications of nanotechnology in connection with innovative industries.
