The Hall effect is the deflection of electrons (holes) in an n-type (p-type) semiconductor with current flowing perpendicular to a magnetic field. The deflection of these charged carriers sets up a voltage, called the Hall voltage, whose polarity depends on the effective charge of the carrier.

Hall effect - Wikipedia

The Hall effect is due to the nature of the current in a conductor. Current consists of the movement of many small charge carriers, typically electrons, holes, ions (see Electromigration) or all three. When a magnetic field is present, these charges experience a force, called the Lorentz force. When such a magnetic field is absent, the charges follow approximately straight paths between collisions with impurities, phonons, etc. However, when a magnetic field with a perpendicular co… TīmeklisV = IBl neA V = I B l n e A. where the upper edge of the strip in Figure 11.17 is positive with respect to the lower edge. We can also combine Equation 11.24 and Equation … TīmeklisThe Hall voltage UHallnow is simply the field in y-direction multiplied by the dimension dyin y-direction. It is clear then that the (easily measured) Hall voltage is a direct measureof the mobility µof the carriers involved, and that its signor polarity will change if the sign of the charges flowing changes.
