Electrical Resistivity of Epitaxial Au Films Surface‐Modulated by Arrays of Pt Nanoparticles

Abstract

Arrays of Pt nanoparticles with a high degree of hexagonal short-range order are deposited by means of self-assembly of diblock-copolymers on top of high quality epitaxial Au films and their influence on the electrical properties is studied. The temperature-dependent resistivity of the nanomodulated Au films is surprisingly well described by the classical size effect model of Fuchs-Sondheimer, which is based on a mixture of diffuse and specular surface scattering events. Especially, no specific influence of the interparticle

Specular electron scattering at single-crystal Cu(001) surfaces

“…4 Recent simulations predict that specular scattering should be achievable for rms roughness below 0.7 nm. 17 From these results, together with the fact that specular scattering has been observed by various researchers for Au surfaces, [18][19][20] we conclude that the primary reason for the reported completely diffuse scattering on Cu surfaces is due to rapid submonolayer oxidation in air.…”
