It is found that the transmission coefficient obtained here is very similar to that obtained by Hahn except that the dependence of the coefficient on the properties of the two metals and of the oxide layer is clearly shown. © 1985.Mahidol UniversityPhysics and AstronomyArticleSCOPUS10.1016/0375-9601(85)90662-0
