Flexible Porous Bismuth Telluride Thin Films with Enhanced Figure of Merit us…

Thermoelectric materials have attracted increasing attention because of their importance in applications such as energy harvesting and electronic cooling devices. [ 1–4 ] The performance of the thermoelectric devices is determined by the fi gure of merit,ZT , defi ned as ZT = S 2 σT / κ , where S is the Seebeck coeffi cient;σ , the electric conductivity; κ , the thermal conductivity; and …
