The Hall Effect set up should provide all operating parameters for the samples and displays the Hall voltage, sample current as well as the sample temperature. The doped Germanium samples should beused to measure the Hall-voltage as a function of the sample current, the magnetic flux density and the sample temperature.
Experiment Examples that should be possible Measurement of Hall voltage as a function of
