Interests
Dr Thomas’ research expertise is in quantum electronics, i.e., the fabrication of devices in which individual or self-assembled quantum objects, such as molecules, act as circuit elements. The aims of his research are to understand how the quantum (electronic/spin, vibrational) states of molecules and their dynamics (how they evolve in time) influence how they conduct electricity, and what new functionalities emerge when electronics are scaled down to nanometre dimensions. He is also interested in exploring wave-particle duality of electrons in two-dimensional materials, such as graphene, through the study of electronic interference effects, with a view to new sensing applications.Publications
