associated temperature (T)-dependent atomic-cohesive-energy and binding-energy-density …

Strength of metals at the Fermi length scale

JN Armstrong, SZ Hua… - physica status solidi (RRL) …, 2012 - Wiley Online Library
Using silver and gold, we have measured the size‐dependence of the yield strength of
atomic‐sized samples as small as a single‐atom bridge, with pico‐level resolution in the …

Evolution of shot noise in suspended lithographic gold break junctions with bias and temperature

R Chen, D Natelson - Nanotechnology, 2016 - iopscience.iop.org
Shot noise is a powerful tool to probe correlations and microscopic transport details that
conductance measurements alone cannot reveal. Even in atomic-scale Au devices that are …
