The transverse thermoelectric effect is a phenomenon that generates thermoelectromotive force in the direction orthogonal to the temperature gradient and has attracted attention as a thermoelectric conversion device that does not require many junction structures. In this study, we have measured the angular dependence of thermoelectric power in MoSi₂, which exhibits the transverse thermoelectric effect due to anisotropic electron and hole conduction originating from its crystal structure. The Seebeck coefficient along the a-axis and the c-axis were obtained from the experimental results of the angular dependence of thermoelectric power and the temperature gradient values read by thermography.
