A large amount of parallel silicon nanowires, placed perpendicularly to a silicon substrate (silicon nanowire forests), has been contacted and assembled in order to fabricate legs of a thermoelectric generator. This paper reports the measurement of the...
Silicon nanowires, whose thermal conductivity is strongly reduced with respect to that of the bulk silicon, are very promising for high-efficient thermoelectric conversion. This work focuses on the development of a technique for the fabrication of...
Nanostructured silicon is a promising material for thermoelectric conversion because the thermal conductivity in silicon nanostructures can be strongly reduced with respect to that of bulk materials. We present thermal conductivity measurements,...
Silicon is a material with very good thermoelectric properties, with regard to Seebeck coefficient and electrical conductivity. Low thermal conductivities, and hence high thermal to electrical conversion efficiencies, can be achieved in nanostructures,...
Conventional techniques for thermal conductivity measurements can lead to unreliable results when applied to nanostructures because heaters and temperature sensors needed for the measurement cannot have a negligible size and therefore perturb the...
We discuss processes for the fabrication of devices for thermoelectric generation, based on silicon nanostructures. The main issue that we address is the design and development of fabrication processes for devices exploiting a large number of...
This paper shows a technique for the fabrication of an electrical (and thermal) contact on the top ends of a large number of vertical silicon nanowires, which are fabricated perpendicularly to a silicon wafer ( silicon nanowire forest). The technique is...
