Journal ArticleDOI
Surface roughness and surface-induced resistivity of gold films on mica: Application of quantitative scanning tunneling microscopy
Raul C. Munoz,Guillermo Vidal,Marcelo Mulsow,Judit Lisoni,Claudio Arenas,Andres Concha,Fernando Mora,Roberto Espejo,German Kremer,Luis Moraga,Rolando Esparza,Patricio Häberle +11 more
TL;DR: In this article, the authors measured the resistivity of a gold film 70 nm thick on mica preheated to 300 \ifmmode^\circ\else\textdegree\fi{}C in UHV, performed between 4 and 300 K, and measured the surface topography of the same film performed with a scanning tunneling microscope.
Journal ArticleDOI
Electron scattering at surfaces and grain boundaries in thin Au films
Ricardo Henríquez,Marcos Flores,Luis Moraga,German Kremer,Claudio Gonzalez-Fuentes,Raul C. Munoz +5 more
TL;DR: In this paper, the electron scattering at surfaces and grain boundaries is investigated using polycrystalline Au films deposited onto mica substrates, and the authors varied independently the film thickness from approximately 50nm to about 100nm.
Journal ArticleDOI
Electron grain boundary scattering and the resistivity of nanometric metallic structures
Ricardo Henriquez,Simón Cancino,Andres Espinosa,Marcos Flores,Thomas Hoffmann,German Kremer,Judit Lisoni,Luis Moraga,Roberto Morales,Simón Oyarzún,Marco Antonio Suárez,Alejandro Zúñiga,Raul C. Munoz +12 more
TL;DR: In this article, the grain size was adjusted to separate the contribution to the resistivity originating in electron-grain boundary scattering, from that arising in electron surface scattering, on gold films approximately 54 nm thick.
Journal ArticleDOI
Surface-induced resistivity of thin metallic films bounded by a rough fractal surface
TL;DR: In this article, the authors extended the modified formalism of Sheng, Xing, and Wang to allow the calculation of the conductivity of a thin metallic film bounded by a rough fractal surface.
Journal ArticleDOI
Surface-induced resistivity of gold films on mica: comparison between the classical and the quantum theory
TL;DR: In this paper, an extension of the theory of Sheng, Xing and Wang (SXW) is presented, which permits the calculation of size effects from statistical properties that characterize the surface on a microscopic scale, for samples in which the average height-height autocorrelation function (ACF) is described either by a Gaussian or by an exponential.
