Abstract: Since the Hall coefficient, Seebeck coefficient, and resistivity of semiconductor materials cannot be tested on the same device and sample, we integrate the Vanderberg method for Hall coefficient and resistivity testing with the quasi-steady-state method for Seebeck coefficient testing, successfully designe an experimental equipment for Hall coefficient, Seebeck coefficient, and resistance measurement of semiconductor materials in the temperature range of room temperature to 573 K. Then, two typical semiconductor materials, including N-type InSb and P-type MnTe, are measured using this equipment as experimental teaching content. This experimental teaching effectively improves the understanding and application of solid state physics’ knowledge of students, thus achieving the organic combination of theoretical teaching and experimental teaching.
