Moiré lattices
A moiré lattice is a periodic interference pattern that occurs when two or more regular patterns overlap, creating a new pattern with a larger unit cell. This phenomenon is commonly observed when two lattice structures, such as layers of two dimensional crystals, with different lattice periodicities or a rotational misalignment, are combined. Moiré superlattices result in new electronic properties that can be manipulated and tuned, making them a versatile platform for the enginnering of quantum states.
We study the realisation of flat electronic bands in graphene and transition metal dichalcogenide heterostructures14 15 as a path towards novel electronic states and superconducting phases.
Our work on tuning superconductivity in moiré lattices is supported by the DFG through the Emmy Noether Programme.
