Higher-order topology in monolayer graphene

WebMonolayer graphene, thin graphite, and hBN flakes (∼10 nm thick) were first exfoliated on an SiO 2 (∼300 nm)/Si substrate, followed by the “tear and stack” technique with a polycarbonate/polydimethylsiloxane stamp to obtain the final hBN/tBLG/hBN/graphite stack. The separated graphene pieces were rotated manually by the twist angle ∼1°.
