Frustrated hopping in an air-stable van der Waals metal
Presented By: Christie Koay
Abstract:
Crystalline systems hosting both strongly correlated and highly mobile electrons have long been sought to study the exotic physical phenomena arising from their interplay. Frustrated lattices such as the dice and Lieb lattices have attracted attention as minimal models that host such properties, but have yet to be identified in crystalline systems. In this talk, I will discuss an air-stable vdW metal that realizes a dice and Lieb-like electronic structure through a novel frustrated hopping model. We assign signatures in electronic transport to features of its electronic structure. We additionally modulate the electronic properties of this material using chemical substitution, reporting two new compounds of its structure type. Finally, I will discuss ongoing work on studying the plasmonic properties of this material.
