On-chip superconducting GHz RF reflectometry of the capacitance response in bilayer graphene
Sung Jin An, Minseo Cho, Minjun Park +12
In dual-gated bilayer graphene, a perpendicular displacement field opens a band gap that modifies both the channel conductance and the electronic compressibility, motivating measur…
Remote Moiré Modulation of Decoupled Dirac Subsystems in Twisted Trilayer Graphene
Dohun Kim, Junsik Choe, Takashi Taniguchi +3
Moiré superlattices are generally assumed to act only at the interface where lattice mismatch or twist occurs. Here, we study charge transport in large-angle helical twisted trila…
Gate-Reconfigurable Single- and Double-Dot Transport in Trilayer MoSe2
Seungwoo Lee, Minjun Park, Yunsang Noh +8
We report gate-controlled quantum-dot transport in a trilayer MoSe2 device that combines a graphite back gate beneath the active region, a separate global gate for conductive acces…
Ferroelectric switching of interfacial dipoles in -RuCl/graphene heterostructure
Soyun Kim, Jo Hyun Yun, Junsik Choe +8
We demonstrate electrically switchable, non-volatile dipoles in graphene/thin hBN/-RuCl heterostructures, stabilized purely by interfacial charge transfer across an atomica…
Correlated interlayer quantum Hall state in large-angle twisted trilayer graphene
Dohun Kim, Gyeoul Lee, Nicolas Leconte +6
Trilayer graphene allows systematic control of its electronic structure through stacking sequence and twist geometry, providing a versatile platform for correlated states. Here we…
Observation of 1/3 fractional quantum Hall physics in balanced large angle twisted bilayer graphene
Dohun Kim, Seyoung Jin, Takashi Taniguchi +4
Magnetotransport of conventional semiconductor based double layer systems with barrier suppressed interlayer tunneling has been a rewarding subject due to the emergence of an inter…
