About the project
Twisted layers of 2D materials allow for new degrees of freedom in quantum matter, leading to novel phenomena such as unconventional ferroelectricity, superconductivity and topological states. This project explores physics of these phase transitions in suspended membranes, measured by advanced nanomechanical and optical probes, to reveal complex phase diagrams within these unique systems.
Twisted layers of 2D materials, such as graphene and hexagonal boron nitride aligned at a specific angle, exhibit new degrees of freedom to tune electron interactions, resulting in the appearance of fascinating states like unconventional ferroelectricity, superconductivity, and topological insulators.
This project will focus on studying transitions between these phases through hybrid nanomechanical and magneto-transport probes and by varying magnetic field, temperature and charge carrier density. By mapping the thermodynamic properties and nanomechanical behaviour across the phase diagram, you will aim to uncover new coupling mechanisms inherent to these quantum material systems.
During your research, you will engage with experimental methods which include:
- high-frequency laser interferometry
- magneto-transport characterization (incl. cryogenic)
- nanoscale fabrication techniques
You will be supported by collaborations with leading experts in 2D materials, nanomechanics and quantum physics. Â By the end of your PhD, you will have gained adeep understanding of phase transitions in 2D and quantum materials and implement it in creating functional devices based on the unique properties of these materials.
Apart from the University of Southampton’s  supervisor, this project also has the following external supervisor:
- Dr Makars Siskins, Institute for Functional Intelligent Materials, National University of Singapore.
