英文摘要	Bi2te3-based alloys have been intensively used for thermoelectric coolers and generators due to their high seebeck coefficient s. so far, efforts to improve the s have been made mostly on changing the structures and components. herein, we demonstrate an anomalous thermoelectricity in strained bi2te3 films, i.e., the value of s is obviously changed after reversing the direction of temperature gradient. further theoretical and experimental analysis shows that it originates from the coupling of thermoelectric and flexoelectric effects caused by a stress gradient. our finding provides a new avenue to adjust the s of bi2te3-based thermoelectric materials through flexoelectric polarization.
