Nanoengineering properties through porous alumina

Abstract

Trabajo presentado en el Nanospain, celebrado en San Sebastian (España), del 7 al 10 de marzo de 2017The understanding of how the properties of the materials, such as thermal conductivity and electrical conductivity, can be tailored by growing nano-scale structures that affect them, is the main aim of this work. The fabrication of nanowires with diameters down to 12 nm and the recent development of threedimensional nanostructured networks based on the controlled pulsed anodization of aluminum [1] open the possibility of tailoring the properties in a certain range. A review of ways of tailoring different properties of materials through nanostructuration with the aid of porous alumina templates will be presented. For instance, in the case of the thermal conductivity, it has been demonstrated how this parameter can be experimentally changed and measured [2]. Moreover, the understanding of the reasons behind this change and how to control from a theoretical point of view has been also pursued. In the case of electrical conductivity, the effect of topological insulating appears in different materials when they are structured at the nano-scale [3].Peer reviewe
