Temperature dependence of transverse planar voltages in laser-irradiated Pt and Pd films

The temperature dependence of laser-induced transverse voltages in Pt and Pd films has been investigated in the range ∼25-300°K. When the data are normalized to a constant average film temperature gradient, a close similarity is found between the normalized values and bulk thermopower data throughout the temperature range. These results suggest a possible model requiring only scalar thermopower coefficients.
