Binary Alloy Simulation

[Tara Mishra]

Dear Prof. Koch,

I am trying to simulate a binary alloy model of Au and Cu nanowire. I wanted to give the exact position of the Cu atoms in the Au lattice and see the effect of position on the HAADF image. Is there any way how I could do it. I tried tinkering with the occupancies but the exact structure of the simulated structure would be indeterminate in this approach. 

Thank You.

Regards

Tara
