WebThis results in a thermal conductivity as low as ∼1.2 W/m-K at 450 K, showing a large thermoelectric figure-of-merit (ZT) of ∼0.46 compared with those of SiGe bulks and even ZT over 2 at 800 K theoretically. All thermoelectric properties were “simultaneously” measured from the same nanowires to facilitate accurate ZT measurements. WebApr 11, 2024 · Thermopower in Si-Ge Alloy Nanowire. In this article, we studied the past and existing research in nanowire (NW) especially based on SiGe NWs. The basic Thermoelectric (TE) principles and theories are introduced and the factors that may influence the TE performance of SiGe NWs are discussed. The superiority of the group IV …
