Direct visualization of gate-tunable flat bands in twisted double bilayer graphene
Souvik Sasmal, Ryan Muzzio, Ahmed Khalifa +12
The symmetry-broken correlated states in twisted double bilayer graphene (TDBG) can be tuned via several external knobs, including twist angle, displacement field, and carrier dens…
Quasiparticle gap renormalization driven by internal and external screening in a WS device
Chakradhar Sahoo, Yann in 't Veld, Alfred J. H. Jones +11
The electronic band gap of a two-dimensional semiconductor within a device architecture is sensitive to variations in screening properties of adjacent materials in the device and t…
Direct view of gate-tunable miniband dispersion in graphene superlattices near the magic twist angle
Zhihao Jiang, Dongkyu Lee, Alfred J. H. Jones +12
Superlattices from twisted graphene mono- and bi-layer systems give rise to on-demand many-body states such as Mott insulators and unconventional superconductors. These phenomena a…
Revealing flat bands and hybridization gaps in a twisted bilayer graphene device with microARPES
Zhihao Jiang, Kimberly Hsieh, Alfred J. H. Jones +7
Controlling the electronic structure of two-dimensional materials using the combination of twist angle and electrostatic doping is an effective means to induce emergent phenomena.…
