Communication: Striking dependence of diffusion kinetics in Ag-Cu nanoalloys upon composition and quantum effects.

The Journal of chemical physics

Asgari M, Negreiros FR, Sementa L, Barcaro G, Behnejad H, Fortunelli A.
PMID: 25084874
J Chem Phys. 2014 Jul 28;141(4):041108. doi: 10.1063/1.4891564.

The kinetics of elemental inter-diffusion in Ag-Cu nanoalloys of 32-34 atoms around 80:20 composition is theoretically investigated by combining analytic-potential and first-principles calculations. An extremely varied behavior is found, with transformation times ranging from tens of nanoseconds to weeks...
