Nonreciprocal thermoelectric cooling by spatially grading Seebeck coefficient for cooling enhancement

Caption

  • An extended figure of merit was proposed considering the total electronic entropy change.
  • A compositionally graded n-type Bi2Te2.7Se0.3 was grown to achieve spatial grading of the Seebeck coefficient.
  • Nonreciprocal thermoelectric cooling and a 10% enhancement were realized in the as-grown single-leg device.
  • The strategy can be applied to any dopable materials, providing a new pathway for thermoelectric cooling.
