Low-frequency Raman signature of Ag-intercalated few-layer MoS
Natalya Sheremetyeva, Drake Niedzielski, Damien Tristant +4
Density functional theory based calculations and experimental analysis on a limited number of real samples are performed to study how the presence of silver intercalated in the van…
Electron-phonon coupling in a magic-angle twisted-bilayer graphene device
Andreij C. Gadelha, Viet-Hung Nguyen, Eliel G. Neto +6
The importance of phonons in the strong correlation phenomena observed in twisted bilayer graphene (TBG) at the so-called magic-angle is under debate. Here we apply gate-dependent…
Semi-empirical many-body formalism of optical absorption in nanosystems and molecules
Antoine Honet, Luc Henrard, Vincent Meunier
A computationally efficient Green's function approach is developed to evaluate the optical properties of nanostructures using a GW formalism applied on top of a tight-binding and m…
Lattice dynamics localization in low-angle twisted bilayer graphene
Andreij C. Gadelha, Douglas A. A. Ohlberg, Cassiano Rabelo +20
A low twist angle between the two stacked crystal networks in bilayer graphene enables self-organized lattice reconstruction with the formation of a periodic domain. This superlatt…
Soliton signature in the phonon spectrum of twisted bilayer graphene
Michael Lamparski, Benoit Van Troeye, Vincent Meunier
The phonon spectra of twisted bilayer graphene (tBLG) are analyzed for a series of 692 twisting angle values in the range. The evolution of the phonon bandstructu…
A Universal Length-Dependent Vibrational Mode in Graphene Nanoribbons
Jan Overbeck, Gabriela Borin Barin, Colin Daniels +13
Graphene nanoribbons (GNRs) have attracted considerable interest as their atomically tunable structure makes them promising candidates for future electronic devices. However, obtai…
