Question 1: CuAu (Copper-Gold) binary alloy crystal consists of N Cu atoms and N Au atoms. The structure can be modelled as follows. At T = OK perfectly ordered system has N Cu-sites occupied by N Cu atoms, and N Au-sites occupied by N Au atoms. At a finite temperature T, n Cu atoms are displaced to Au-sites, and n Au atoms are displaced to Cu-sites. For one site exchange & is given to the crystal. Find the energy of the system as a function of temperature [E(T)] in microcanonical ensemble.
