Resistivity Response to Stress and Strain of a Flexible Bi2Te3 Based Thermoelectric Material

Abstract

Here we report about the synthesis of Bi2Te3 based flexible thermoelectric materials and the response of the electrical resistivity to tensile and compressive stress. As a template fiber spun polymers have been used onto which a thin composite film of graphene and Bi2Te3 nanoplates was deposited. The Bi2Te3 nanoplates were synthesized using the polyol method. Upon straining the material, the resistivity dropped which is attributed to the increased contact between the individual wires.
