Alloying behaviour in Cu-Pd nanostructures

Monte Carlo simulation procedure has been used to study the alloying behavi our in Cu-Pd cubo-octahedral nanostructures as a function of temperature. h eat of mixing and the cluster size. Alloying is found to increase with incr ease in negative heat of mixing and with temperature. For a fixed value of the heat of mixing the alloying is found in general to increase with cluste r size. All these results are in full agreement with the experimental obser vations. (C) 2001 Elsevier Science B.V. All rights reserved.
