Stephen Carr (CMT) Moiré patterns in 2D materials

Controlling the relative twist angle between successive layers in two-dimensional materials offers an approach to manipulating their electronic properties: “twistronics.” For arbitrary twisting angles, the resulting moiré patterns contain thousands of atoms and generally lack symmetry, making them challenging to understand. But the emerging structures show many exciting phenomenon: quasicrystals, domain-wall formation, and superconductivity. I will discuss the construction of accurate multiscale models for these systems along with an exploration of how to engineer desired electronic properties.
