Photoinduced twist and untwist of moiré superlattices in TMDC heterobilayers

C. J. R. Duncan, A. C. Johnson, I. Maity +15

Two-dimensional moiré materials are formed by artificially stacking atomically thin monolayers. A wealth of correlated and topological quantum phases can be engineered via precise…
