Project description
Advanced artificial DNA moiré superlattices
Moiré patterns arise from stacked sublattices with slightly mismatched lattice constants or orientations, producing superlattices of larger periodicity. Experiments with nanometre-scale moiré superlattices are lacking, though they resemble twisted Van der Waals and nanophotonic systems. The ERC-funded DMoS project aims to create DNA moiré superlattices that bridge the gap between the angstrom and submicron length scales. These structures will help explore the fundamental question of how structure influences function. The project will investigate the relationship between structure and function in spintronic and optical systems, focusing on how the features of DNA moiré superlattices affect spin polarisation and lattice-dependent optical chirality. This interdisciplinary approach opens new avenues in structural design and functionality, paving the way for innovative nanostructured devices.
Objective
Moiré patterns are commonly observed phenomena across all length scales. A moiré pattern arises from the spatial modulation of stacked sublattices, which have slightly different lattice constants and/or orientations. This pattern forms a superlattice with a larger periodicity, spanning multiple unit cells of the sublattices.
To date, moiré superlattices comprising sublattices with lattice constants of several nanometers have not been experimentally realized. Moiré superlattices at this length scale do not have counterparts in naturally occurring materials, but represent analogues to twisted van der Waals and twisted nanophotonic systems. This DMoS project aims to underscore a pinnacle in DNA nanotechnology by creating entirely new, artificial moiré superlattices that bridge the gap between the angstrom and submicron length scales. These DNA moiré superlattices with precisely engineered structural features will provide a fertile ground for addressing a fundamental question in nature: ‘How does structure influence function?’
By pushing the boundaries of what is possible in structural control at the nanoscale, DMoS is set to explore the intricate relationship between structure and function in both spintronic and optical systems - fields that require precise manipulation of spin and light. Specifically, DMoS will investigate how the structural features of DNA moiré superlattices influence spin polarization in chirality-induced spin selectivity and explore their structural impact on lattice-dependent optical chirality in moiré chiral metamaterials. This fusion of interdisciplinary expertise opens new frontiers in structural design and functionality, with implications beyond the current state of the art. Ultimately, DMoS aims to transform our understanding of how nanoscale features can be engineered to achieve targeted functionalities, setting the stage for a new generation of nanostructured devices with far-reaching applications in science and technology.
