Flexible Porous Bismuth Telluride Thin Films with Enhanced Figure of Merit using Micro-Phase Separation of Block Copolymer
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 T , the temperature. To date, thermoelectric devices have been too ineffi cient to be cost effective in most applications. Many attempts have been made to enhance ZT using nanostructured materials. It has been increasingly recognized that thermal conductivity in nanostructured materials is not an intrinsic parameter, unlike for bulk materials.
