Magnetic field stabilized Wigner crystal states in a graphene moiré superlattice
Guorui Chen, Ya-Hui Zhang, Aaron Sharpe +11
Wigner crystals are predicted as the crystallization of the dilute electron gas moving in a uniform background when the electron-electron Coulomb energy dominates the kinetic energ…
Spectroscopy Signatures of Electron Correlations in a Trilayer Graphene/hBN Moiré Superlattice
Jixiang Yang, Guorui Chen, Tianyi Han +12
ABC-stacked trilayer graphene/hBN moiré superlattice (TLG/hBN) has emerged as a playground for correlated electron physics. We report spectroscopy measurements of dual-gated TLG/hB…
Tunable ferromagnetism at non-integer filling of a moiré superlattice
Guorui Chen, Aaron L. Sharpe, Eli J. Fox +12
The flat bands resulting from moiré superlattices in magic-angle twisted bilayer graphene (MATBG) and ABC-trilayer graphene aligned with hexagonal boron nitride (ABC-TLG/hBN) have…
Visualization of the flat electronic band in twisted bilayer graphene near the magic angle twist
M. Iqbal Bakti Utama, Roland J. Koch, Kyunghoon Lee +15
Bilayer graphene was theorized to host a moire miniband with flat dispersion if the layers are stacked at specific twist angles known as the magic angles. Recently, such twisted bi…
Tunable Correlated Chern Insulator and Ferromagnetism in Trilayer Graphene/Boron Nitride Moiré Superlattice
Guorui Chen, Aaron L. Sharpe, Eli J. Fox +12
Studies on two-dimensional electron systems in a strong magnetic field first revealed the quantum Hall (QH) effect, a topological state of matter featuring a finite Chern number (C…
Signatures of Gate-Tunable Superconductivity in Trilayer Graphene/Boron Nitride Moiré Superlattice
Guorui Chen, Aaron L. Sharpe, Patrick Gallagher +12
Understanding the mechanism of high temperature (high Tc) superconductivity is a central problem in condensed matter physics. It is often speculated that high Tc superconductivity…
Evidence of Gate-Tunable Mott Insulator in Trilayer Graphene-Boron Nitride Moiré Superlattice
Guorui Chen, Lili Jiang, Shuang Wu +9
Mott insulator plays a central role in strongly correlated physics, where the repulsive Coulomb interaction dominates over the electron kinetic energy and leads to insulating state…
