Non parabolic band structure proposed by the Single Kane Band (SKB) model is able to explain the optical and thermoelectric properties of Dysprosium (Dy) doped Zinc oxide (ZnO) thin films coated by reactive radio frequency (RF) magnetron sputtering. Thermoelectric devices which are optically transparent possess a good promise for the future energy application. The excessive number of carriers formed by chemical substitution of Dy ion in the host ZnO lattice results in the band filling and cause heavier effective mass for the bands. Anomalous drifting of effective mass from 0.25 m_e to 1.80 m_e reduces the mobility of free charge carriers in the deformed potential. Multifunctionality of oxide thin films as transparent conducting oxide (TCO) and thermoelectric (TE) material can be consistent through band filling. Band filling leads to the widening of optical band gap and the heavier effective mass for the improved thermoelectric properties. N type thermoelectric thin films of Dy doped ZnO have been developed in order to maximize the optical transparency (>70% in the visible region), electrical conductivity (σ > 500 S/m at 473 K) and thermoelectric power factor (>25 μW/mK² at 473 K).

单凯恩带（SKB）模型提出的非抛物线带结构能够解释通过反应性射频（RF）磁控溅射涂覆的掺（（Dy）的氧化锌（ZnO）薄膜的光学和热电性质。光学透明的热电器件对未来的能源应用具有良好的前景。通过主体ZnO晶格中Dy离子的化学取代形成的过多载流子导致能带填充，并导致能带的有效质量增加。有效质量从0.25 m _e到1.80 m _e的异常漂移降低了自由电荷载流子在变形电势中的迁移率。氧化物薄膜作为透明导电氧化物（TCO）和热电（TE）材料的多功能性可以通过填充带来保持一致。带填充导致光学带隙的扩大和有效质量的增加，从而改善了热电性能。为了最大程度地提高光学透明度（在可见光区域> 70％），电导率（在473 K下σ> 500 S / m）和热电功率因数（> 25μW），已开发出掺Dy的ZnO的N型热电薄膜。 / mK ² at 473 K）。
