[We-A2-B-04] Berry Phase Transition in Folded Bilayer Graphene

〇Hannes Kakuschke¹, Lina Bockhorn¹, Rolf J. Haug¹ (1. Leibniz Univ. Hannover (Germany))

In bilayer graphene folded around hBN, we observe a spatial evolution of the Berry phase from 2π far away from the fold to π at the folded edge, attributed to curvature-induced distortions of the stacking order.
