a) Given the data for the vacancy formation, interstitial formation, and binding energies for copper (EV = 20 kCal/mol, Ei = 90 kCal/mol, and B = 7 kCal/mol), depict the temperature dependence between 300 oC and just slightly below the melting point, 1083 oC, of the concentrations of monovacancies, divacancies and self-interstitials
