Imaging supermoiré relaxation in helical trilayer graphene
Jesse C. Hoke, Yifan Li, Yuwen Hu +5
In twisted van der Waals materials, local atomic relaxation can alter the underlying electronic structure. Characterizing lattice reconstruction and its susceptibility to strain is…
Link between thermodynamic correlation signatures and superconductivity in twisted trilayer graphene
Jesse C. Hoke, Yifan Li, Yuwen Hu +6
Twisted graphene multilayers exhibit strong electronic correlations, which manifest in a range of experimental signatures. Yet how these signatures relate to each other and the mic…
High-Resolution Tunneling Spectroscopy of Fractional Quantum Hall States
Yuwen Hu, Yen-Chen Tsui, Minhao He +8
Strong interaction between electrons in two-dimensional systems in the presence of a high magnetic field gives rise to fractional quantum Hall states that host quasiparticles with…
High spatial resolution charge sensing of quantum Hall states
Cheng-Li Chiu, Taige Wang, Ruihua Fan +5
Charge distribution offers a unique fingerprint of important properties of electronic systems, including dielectric response, charge ordering and charge fractionalization. We devel…
