Arenas, Claudio; Henríquez, Ricardo; Moraga, Luis; Muñoz, Enrique; Muñoz, Raúl (Elsevier, 2015)We calculate the electrical resistivity of a metallic specimen, under the combined effects of electron scattering by impurities, grain boundaries, and rough surfaces limiting the film, using a quantum theory based upon the ...

Moraga, Luis; Arenas, Claudio; Henríquez, Ricardo; Solís, Basilio (Wiley, 2015)We report a new formula for the electrical conductivity of a thin wire of rectangular cross-section, obtained from an exact solution of the Boltzmann equation by assuming perfectly diffuse surface scattering and absence ...

Henríquez, Ricardo; Cancino, Simón; Espinosa, Andrés; Flores Carrasco, Marcos; Hoffmann, Michael; Kremer Erdmann, Germán; Lisoni Reyes, Judith; Moraga, Luis; Morales, Roberto; Oyarzún, Simón; Suárez, Marco; Zúñiga Páez, Alejandro; Muñoz Alvarado, Raúl (AMER PHYSICAL SOC, 2010-09-23)The resistivity of metallic structures depends on both electron-grain boundary scattering and electron-surface scattering. By tuning the grain size, we have been able to separate the contribution to the resistivity ...

Parra, Carolina; Montero Silva, Francisco; Henríquez, Ricardo; Flores Carrasco, Marcos; Garín, Carolina; Ramírez, Cristian; Moreno, Macarena; Correa, Jonathan; Seeger, Michael; Häberle, Patricio (American Chemical Society, 2015)Understanding biological interaction with graphene and hexagonal-boron nitride (h-BN) membranes has become essential for the incorporation of these unique materials in contact with living organisms. Previous reports show ...
