Published in 2025 at "Advanced materials"

DOI: 10.1002/adma.202514744

Abstract: Sublattice symmetry in graphene governs its Dirac semimetal behavior, where electrons exhibit linear dispersion, limiting its potential for technological applications. Here, moiré ferroelectricity in twisted WSe2 (t-WSe2) is exploited to break graphene's sublattice symmetry, inducing… read more here.

Published in 2024 at "Advanced Science"

DOI: 10.1002/advs.202402464

Abstract: Phase transitions are typically quantified using order parameters, such as crystal lattice distances and radial distribution functions, which can identify subtle changes in crystalline materials or high‐contrast phases with large structural differences. However, the identification… read more here.
