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 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…
