Length dependence of thermal conductivity by approach-to-equilibrium molecular dynamics

Hayat Zaoui, Pier Luca Palla, Fabrizio Cleri, Évelyne Martin

The length dependence of thermal conductivity over more than two orders of magnitude has been systematically studied for a range of materials, interatomic potentials, and temperatures using the atomistic approach-to-equilibrium molecular dynamics (AEMD) method. By comparing the values of…

Wetting characterization of high aspect ratio nanostructures by gigahertz acoustic reflectometry

Christophe Virgilio, Julien Carlier, Pierre Campistron, Malika Toubal, Philippe Garnier, L. Broussous, V. Thomy, Bertrand Nongaillard

Wetting efficiency of microstructures or nanostructures patterned on Si wafers is a real challenge in integrated circuits manufacturing. In fact, bad or non-uniform wetting during wet processes limits chemical reactions and can lead to non-complete etching or cleaning inside the patterns and device…
