Growth optimization and device integration of narrow-bandgap graphene nanoribbons
Gabriela Borin Barin, Qiang Sun, Marco Di Giovannantonio +26
The electronic, optical and magnetic properties of graphene nanoribbons (GNRs) can be engineered by controlling their edge structure and width with atomic precision through bottom-…
QED theory of electron beam-induced electronic excitation and its effect on sputtering cross sections in 2D crystals
Anthony Yoshimura, Michael Lamparski, Joel Giedt +6
Many computational models have been developed to predict the rates of atomic displacements in two-dimensional (2D) materials under electron beam irradiation. However, these models…
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…
Electronic localization in small-angle twisted bilayer graphene
V. Hung Nguyen, D. Paszko, M. Lamparski +3
Close to a magical angle, twisted bilayer graphene (TBLG) systems exhibit isolated flat electronic bands and, accordingly, strong electron localization. TBLGs have hence been ideal…
Machine-learning models for Raman spectra analysis of twisted bilayer graphene
Natalya Sheremetyeva, Michael Lamparski, Colin Daniels +2
The vibrational properties of twisted bilayer graphene (tBLG) show complex features, due to the intricate energy landscape of its low-symmetry configurations. A machine learning-ba…
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…
Engineering Three-Dimensional (3D) Out-of-Plane Graphene Edge Sites for Highly-Selective Two-Electron Oxygen Reduction Electrocatalysis
Daniel San Roman, Dilip Krishnamurthy, Raghav Garg +4
Selective two-electron oxygen reduction reaction (ORR) offers a promising route for hydrogen peroxide synthesis, and defective sp2 carbon-based materials are attractive, low-cost e…
