Influence of Bulk Concentration on the Discontinuous Transition in Surface Segregation

Article Preview

Abstract:

The discontinuous transition of surface concentration due to the change of bulk concentration in isosteric/isothermal surface segregation has been discussed quantitatively according to the modified Darken model. The criteria for observing the discontinuous transition in surface segregation has been derived on the basis of the Bragg-William expression.
