Thesis title: Design and properties of artificial mesoscopic semiconductor lattices
My PhD project investigates the possibility of using artificial lattices to engineer the material properties. Specifically, the focus lies on the study and design of electron correlations, encoded in the Hubbard model, whose understanding is arguably one of the most outstanding questions in condensed matter physics. Moreover, the project aims to explore the possibility to generate artificial gauge fields which mimic real magnetic or electric fields, yet with the potential to be significantly more localized and intense than those achievable in conventional experiments.
To realize ultra-uniform artificial semiconductor lattices, I am pursuing two distinct approaches. The first involves the fabrication of superlattices using 2D heterostructures, while the second employs a network of nanowires Additionally, the research extends to the study of superlattices and artificial gauge fields in graphene, in collaboration with DTU Physics. The use of two distinct fabrication approaches, together with the investigation of graphene devices, not only allows for a comparative analysis but also enhances the chances of achieving superlattices with tunable electron properties related. Any results in this direction would be of the outermost scientific importance.
