For room temperature we found the relative Seebeck coefficient of $S_{\\beta\\text{-Ga}_2\\text{O}_3\\text{-Al}}=(-300\\pm20)\\;\\mu$V/K. At high bath temperatures $T>240$ K, the scattering is determined by electron-phonon-interaction. At lower bath temperatures between $T=100$ K and $T=300$ K, an increase in the magnitude of the Seebeck coefficient is explained in the frame of Strattons formula.
