Abstract: With digital computer control and data acquisition system, this paper carried out the Ge single crystal （6.0 mm long, 4.0 mm wide, 0, 6 mm thick） Hall effect from 77 K to 420 K, attained Hall coefficient RH （T）, Hall conductivity σ（T）, and Hall mobility μH（T） of the temperature dependence through analysis of the Hall voltage. This experiment results make a full impact for students on comprehending the knowledge of semiconductor physics.

Key words: Hall effect at different temperatrues, Hall coefficient, data analysis
