Evidence for electron localisation in a moiré-of-moiré superlattice
Hangyeol Park, Junhyeok Oh, Rasoul Ghadimi +7
The localisation of electrons in a lattice potential is an quantum-mechanical phenomenon and is often associated with remarkable physical properties of solids involving electron sp…
Local thermodynamic DOS measurement and twist-angle mapping in graphene-hBN superlattices
Namkyung Lee, Hangyeol Park, Seungwon Jung +3
Moiré patterns arising from twisted van der Waals stacks fundamentally reshape their electronic properties, enabling band-structure engineering that has driven rapidly growing inte…
Characterization of a graphene-hBN superlattice field effect transistor
Won Beom Choi, Youngoh Son, Hangyeol Park +5
Graphene provides a unique platform for hosting high quality 2D electron systems. Encapsulating graphene with hexagonal boron nitride (hBN) to shield it from noisy environments off…
Interplay of valley, layer and band topology towards interacting quantum phases in moiré bilayer graphene
Yungi Jeong, Hangyeol Park, Taeho Kim +4
In Bernal-stacked bilayer graphene (BBG), the Landau levels give rise to an intimate connection between valley and layer degrees of freedom. Adding a moiré superlattice potential e…
