Thermal conductivity, nanowires, geometry, thermoelectrics

The fabrication of 3D nanowire networks via electrochemical deposition in interconnected porous alumina templates has given rise to a novel nanostructure which presents properties that differ from the bulk original material. In some cases, such as for the thermal conductivity, the properties have shown dependence from the geometry of the structure, which can be tailored at will. In this talk, I will present our first results obtained with bismuth telluride 3D nanowire networks and its promising relevance for thermoelectric applications.
