Scanning-tunnelling microscopy and spectroscopy of single-layer transition-metal dichalcogenides

Lead Research Organisation: University of St Andrews
Department Name: Physics and Astronomy

Abstract

Quantum materials offer a wide range of technologically interesting and relevant properties, few of which have so far been realized and explored for device operation. One reason for this is that their properties are typically studied on single crystals, whereas practically all current device technology builds on thin films and heterostructures. Growth of quantum materials in thin film form using molecular beam epitaxy provides a path to realize their opportunities for device applications, but require the growth protocols and the properties of their thin film version to be studied and understood first. In this project, a low temperature scanning tunnelling microscope optimized for the study of monolayer and thin film samples will be built and used to study the properties of monolayer transition metal dichalcogenides (TMDCs). The interplay between reduced dimensionality, spin-orbit coupling, charge density wave orders and superconductivity provides a vast playground to explore their fundamental properties and stabilize novel exotic correlated ground states, and affords new opportunities to control their ground state which may open up avenues for applications.

Specialist training will be provided via the introductory courses of the Centre for Doctoral Training in Quantum Materials, graduate taught courses of the University of St Andrews, and through transferrable skills training offered by the Centre for Academic, Professional and Organisational Development, training organised via the CDTs and via external providers.
