Can anyone tell me about Cu-Au NPs, and why Au occupies the shell rather than core?

05 May 2014 1 5K Report

The cohesive energy of Au is higher than Cu, but still putative DFT global minimizations have been reported in the Cu-core and Au-shell. Are we allowed to explain this according to strain relief effects?

P. Anandha Ganesh

I suggest you to have a look on this paper, because the strain effects of AuCu were explained in detail. I hope this will help you...
