Electric Field-Induced Hole- and Electron-Type Flat Bands in Twisted Double Bilayer Graphene
Zhihao Jiang, Dongkyu Lee, Alfred J. H. Jones +11
Application of a finite electric field and small twist angle between two graphene bilayers leads to widely tunable electronic structures that support emergent phenomena. Here, we m…
Spectroscopic signatures of persistent exciton condensation in a bulk magnetic topological insulator
Paulina Majchrzak, Chakradhar Sahoo, Manuel Tuniz +7
Exciton condensates are long-sought correlated quantum states arising from macroscopic coherence of bound electron-hole pairs. Although equilibrium and transient excitonic states h…
Observation of dodecagonal replica bands in 30-twisted bilayer WSe
Christian Valentiner-Branth Fokdal, Chakradhar Sahoo, Thomas S. Nielsen +6
Twisted bilayers of two-dimensional (2D) transition metal dichalcogenides are promising systems for achieving tunable quasicrystalline orders with emergent properties. The underpin…
Band offsets and stability of WSe/RuCl van der Waals charge-transfer contacts
Thomas S. Nielsen, Edvard Solbrekken, Christian Overby +7
The layered Mott insulator -RuCl induces degenerate hole-doping in two-dimensional semiconductors due to its large electron affinity, making it a promising charge-transfer m…
Direct nanoscale mapping of band alignment in single-layer semiconducting lateral heterojunctions
Chakradhar Sahoo, Suman Kumar Chakraborty, A. Kousika +15
Atomic-scale control over band alignment in single-layer lateral heterostructures (LHSs) of dissimilar transition metal dichalcogenides (TMDCs) is critical for nextgeneration elect…
Multi Moire Networks in Engineered Lateral Hetero-Bilayers: Programmable Phononic Reconfiguration and Second Harmonic Generation
Suman Kumar Chakraborty, Frederico B. Sousa, Chakradhar Sahoo +14
Moire engineering in two-dimensional transition metal dichalcogenides enables access to correlated quantum phenomena. Realizing such effects demands simultaneous control over twist…
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.…
