|Issue Date:||10-Sep-1995||Citation:||Yong, Y.C.,Poon, H.C. (1995-09-10). Size-mismatch effect on the surface segregation of AuCu3 alloys. Surface Science 338 (1-3) : L825-L832. ScholarBank@NUS Repository.||Abstract:||A microscopic electronic theory is presented for the study of surface segregation of transition metal alloys. The total energy is written as a sum of attractive band structure energy and repulsive Born-Mayer-type interaction. The size-mismatch effect is treated within this electronic model instead of being introduced as a parameter. Through minimization of the surface free energy, the equilibrium concentration profile and surface relaxation of different faces of AuCu3 are obtained as a function of temperature and compared with experimental data by low energy ion scattering (LEIS). © 1995.||Source Title:||Surface Science||URI:||http://scholarbank.nus.edu.sg/handle/10635/97954||ISSN:||00396028|
