通过控制NaxCoO2热电薄膜的结晶度和平均晶粒尺寸，实现了热电功率因数的翻倍，同时对导热系数有较强的抑制作用。这些结构工程的NaxCoO2薄膜在室温下的性能优于单晶和多晶样品，并展示了热电氧化物薄膜的潜力。©2014 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim。
By controlling the crystallinity and average grain size of thermoelectric NaxCoO2 thin films, a doubling of the thermoelectric power factor is achieved in combination with a strong suppression of the thermal conductivity. These structurally engineered NaxCoO2 thin films outperform single crystalline and polycrystalline samples at room temperature and demonstrate the potential of thermoelectric oxide thin films. © 2014 WILEY-VCH Verlag GmbH & Co.
