Abstract

Flexible porous bismuth telluride thin films are prepared using micro-phase separated block-copolymer porous films. The thermal conductivities of the thus-fabricated porous p-type (Bi0.4Te3.0Sb1.6) and n-type (Bi2.0Te2.7Se0.3) thin films are extremely lower than those of their bulk counterparts owing to strong phonon scattering. The figure of merit ZT of porous p-, n- bismuth telluride thin films is estimated to be 1.34 and 1.47.
