This phenomenon is called Hall Effect. At equilibrium, a voltage appears at the semiconductor edges. A current Iis arranged to flow through the strip from left to right, and the voltage difference between the top and bottom is measured. The Hall effect describes what happens to current flowing through a conducting material - a metal, a semiconductor - if it is exposed to a magnetic field B. The Hall Effect The Hall effect describes the behavior of the free carriers in a semiconductor whenapplying an electric as well as a magnetic field. This means that the output signal produced by a Hall effect sensor is a function of magnetic field density around it. The Hall effect is the production of a voltage difference (the Hall voltage) across an electrical conductor, transverse to an electric current in the conductor and a magnetic field perpendicular to the current. The Hall Effect set up provides all operating parameters for the samples and displays the Hall voltage, sample current as well as the sample temperature. 3. Hall effect in semiconductors When a current-carrying semiconductor is kept in a magnetic field, the charge carriers of the semiconductor experience a force in a direction perpendicular to both the magnetic field and the current.
