WebbHowever, as-grown electrodeposited Bi2Te3-ySey films typically have a Seebeck coefficient around a third of the bulk value, which sometimes can be improved with thermal annealings. In this work, we report as-grown Bi2Te3-ySey films having a Seebeck coefficient of approximately half the value of bulk without additional thermal treatments.

Webb摘要： Enhancement of the Seebeck coefficient (S ) without reducing the electrical conductivity (sigma) is essential to realize practical thermoelectric materials exhibiting a dimensionless figure of merit (ZT=S2 x sigma x T x kappa-1) exceeding 2, where T is the absolute temperature and kappa is the thermal conductivity. Webb13 apr. 2024 · The electrical conductivity and Seebeck coefficient were measured over the temperature range of 423 ≤ T/K ≤ 573. A current of 20 mA was used for the conductivity measurements, and a maximum gradient of 50 K was maintained between the upper and lower electrodes for the measurement of the Seebeck coefficient.
