Aluminium Nanowires: Influence of Work Hardening on Conductance Histograms
arXiv:0707.1336 · doi:10.1103/PhysRevB.77.033411
Abstract
Conductance histograms of work-hardened Al show a series up to 11 equidistant peaks with a period of 1.15 +/- 0.02 of the quantum conductance unit G_0 = 2e^2/h. Assuming the peaks originate from atomic discreteness, this agrees with the value of 1.16 G_0 per atom obtained in numerical calculations by Hasmy et al.
