competition between the crystal growth in the planar direction and the nucleation in radial direction
The films with such special structure also exhibit attractive thermoelectric properties.
Optimal TE properties were obtained in the film with oriented layered structure with Seebeck coefficient S ∼ −70 μV/K at room temperature, −85 μV/K at 450 K, and power factor 8.8 μW/cm K2 at room temperature, 11.4 μW/cm K2 at 450 K, respectively.
