Abstract
The transverse thermoelectric effect in HTSC films was analyzed theoretically concerning a plausible anisotropic electron-band structure which was supposed to be weakly binding in Cu O layers and tightly binding in the directions close to the c-axis. We have found interesting peculiarities in the effect value as a function of the Fermi energy in the vicinity of the points which correspond to the boundaries of Brillouin zones along the c-axis direction. At the first-zone boundary the effect is 5 times greater than its initial value. Then, if many zones are taken into account, it demonstrates a nonmonotone behavior strongly depending on the band parameters (energy band widths and gaps) with a possible change in the sign of the effect.
