Size-dependent Structural Disorder in Nanocrystalline Cu Probed by Synchrotron-based X-ray Techniques

Johannessen, Bernt; Kluth, Patrick; Cookson, D J; Foran, Garry J; Ridgway, Mark C


Elemental Cu nanocrystals were synthesized in thin film SiO2 by ion implantation and thermal annealing. The local atomic structure and nanocrystal size distribution were investigated by means of extended X-ray absorption fine structure (EXAFS) spectroscopy and small angle X-ray scattering (SAXS), respectively. We quantify the bondlength contraction and increased structural disorder in the nanocrystals as compared to a bulk Cu reference. Both are proportional to the inverse of the nanocrystal...[Show more]
