Abstract: Extended x-ray absorption fine structure (EXAFS) spectroscopy has emerged as an invaluable synchrotron radiation technique for determining the short-range atomic structure in a vast range of diverse materials. Cu nanocrystals (NCs) were synthesised by high-energy ion beam implantation and thermal annealing. We present results of EXAFS measurements determining the first nearest neighbour Cu environment and quantify significant concentration- and annealing-temperature-dependent structural perturbations as compared to a bulk Cu standard. In particular we observe and explain an enhanced structural disorder involving both a suppressed coordination number and bondlength contraction.
