Definition of the Hall effect :
When a current passes through a bar of semiconductor (or conductive) material, and if an inductive magnetic field B is applied perpendicular to the direction of current flow, a voltage, called Hall voltage, proportional to the magnetic field and current appears on the side faces of the bar.
This tension is proportional to the displacement speed of the charge carriers, which is considerably greater in semiconductor materials than in metal conductors.
