Experiments in Modern Physics The Hall Effect and Conductivity in Germanium Rex Tayloe Department of Physics, Indiana University 10/9/03 Last Revised: 2/19/04 Goals : Measure the Hall Voltage and conductivity for Germanium as a function of temperature. Introduction Semiconductors exhibit several interesting effects that will be investigated in this lab. The theoretical background for this experiment is discussed at length in Refs [1-3]. Equipment - Hall effect apparatus which consists of a sample box with temperature and magnetic field control. - Temperature measurement and control electronics. - Low-voltage power supply. - Several digital multimeters. Preparation - Read Ref. [1] p304ff. References [2-3] also contain good descriptions and should be consulted especially for the analysis. Experiment - Examine the setup. Measure the dimensions of the sample, be sure to understand the labeling of the circuit contacts and the orientation in the magnetic field. Document this well.
