Renormalization Group Treatment for O/W(110).

Abstract

We consider the lattice gas model of the O/W(110) chemisorption system. We calculate the transition temperature T sub c at one half coverage by means of a new renormalization group treatment. Good agreement (< or = 10%) with T sub c obtained via Monte Carlo studies is found over a wide range of parameter values. We explore the remarkable independence of T sub c from epsilon sub 1, the nearest neighbor adatom-adatom interaction. We also give several arguments indicating that the transition at this coverage is in the simple Ising universality class. (Author)
