Spectroscopic size and thickness metrics for liquid-exfoliated h-BN
Aideen Griffin, Andrew Harvey, Brian Cunningham +8
For many 2D materials, optical and Raman spectra are richly structured, and convey information on a range of parameters including nanosheet size and defect content. By contrast, th…
Non-conservative current-driven dynamics: beyond the nanoscale
Brian Cunningham, Tchavdar N. Todorov, Daniel Dundas
Long metallic nanowires combine crucial factors for non-conservative current-driven atomic mo- tion. These systems have degenerate vibrational frequencies, clustered about a Kohn a…
Length matters: keeping atomic wires in check
Brian Cunningham, Tchavdar N. Todorov, Daniel Dundas
Dynamical effects of non-conservative forces in long, defect free atomic wires are investigated. Current flow through these wires is simulated and we find that during the initial t…
Nonconservative dynamics in long atomic wires
Brian Cunningham, Tchavdar N. Todorov, Daniel Dundas
The effect of nonconservative current-induced forces on the ions in a defect-free metallic nanowire is investigated using both steady-state calculations and dynamical simulations.…
An ignition key for atomic-scale engines
Daniel Dundas, Brian Cunningham, Claire Buchanan +3
A current-carrying resonant nanoscale device, simulated by non-adiabatic molecular dynamics, exhibits sharp activation of non-conservative current-induced forces with bias. The res…
