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…
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…
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…
