Anisotropic Seebeck and magneto-Seebeck coefficients of Bi and BiSb alloy thin films

Abstract

We have grown Bi and BiSb alloy thin films at an oblique angle on (211) CdTe substrates, which were tilted by 19/spl deg/ to the trigonal axis. We have studied the anisotropic Seebeck and magneto-Seebeck coefficients in magnetic fields of 0-0.7T and have observed a strong dependence on the crystal-axis and the magnetic field direction in Seebeck coefficients.
