Data analysis on the Ge single crystal Hall effects at different temperatures

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.
