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…
An Environmentally Stable and Lead-Free Chalcogenide Perovskite
Tushar Gupta, Debjit Ghoshal, Anthony Yoshimura +14
Organic-inorganic halide perovskites are intrinsically unstable when exposed to moisture and/or light. Additionally, the presence of lead in many perovskites raises toxicity concer…
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…
In-Plane Breathing and Shear Modes in Low-Dimensional Nanostructures
Dan Liu, Colin Daniels, Vincent Meunier +2
We use continuum elasticity theory to revise scaling laws for radial breathing-like and shear-like vibration modes in quasi-2D nanostructures including finite-width nanoribbons and…
Optimized substrates and measurement approaches for Raman spectroscopy of graphene nanoribbons
Jan Overbeck, Gabriela Borin Barin, Colin Daniels +13
The on-surface synthesis of graphene nanoribbons (GNRs) allows for the fabrication of atomically precise narrow GNRs. Despite their exceptional properties which can be tuned by rib…
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…
