Superconductivity near quarter and half filling of a strongly correlated triangular Hubbard band in twisted trilayer WSe2
Yungi Jeong, Kenji Watanabe, Takashi Taniguchi +1
The triangular-lattice Hubbard model is one of the paradigmatic settings for studying correlated electronic systems with geometric frustration that can give rise to a variety of ph…
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…
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…
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…
