Nanostructured supplies current improved thermoelectric properties as a consequence of non-trivial results on the nanoscale. Nevertheless, the characterization of particular person nanostructures, particularly from the thermal viewpoint, remains to be an unsolved matter. This work presents the whole structural, morphological, and thermoelectrical analysis of the selfsame particular person bottom-up built-in nanowire using an revolutionary micro-machined system appropriate with transmission electron microscopy whose fabrication can also be mentioned. Due to a design that arranges the nanostructured samples utterly suspended, detailed structural evaluation utilizing transmission electron microscopy is enabled. In the identical system structure, electrical collectors and remoted heaters can be found at each ends of the trenches for thermoelectrical measurements of the nanowire i.e. thermal and electrical properties concurrently. This enables the direct measurement of the nanowire energy issue. Moreover, micro-Raman thermometry measurements had been carried out to judge the thermal conductivity of the identical suspended silicon nanowire. A thermal profile of the self-heating nanowire might be spatially resolved and used to compute the thermal conductivity. On this work, heavily-doped silicon nanowires had been grown on this microdevices yielding a thermal conductivity of 30.8 ± 1.7 W Km−1 and an influence issue of two.8 mW mK−2 at a median nanowire temperature of 400 Okay. Notably, no thermal contact resistance was noticed between the nanowire and the majority, confirming the epitaxial attachment. The system introduced right here reveals outstanding utility within the difficult thermoelectrical characterization of built-in nanostructures and within the growth of a number of gadgets comparable to thermoelectric turbines.
