The essence of the Hall effect: When the carriers in the solid material move in the applied magnetic field, the trajectory shifts due to the Lorentz force, and charge accumulation occurs on both sides of the material, forming an electric field perpendicular to the current direction; Finally, the Lorentz force of the carrier is balanced with the electric field repulsion, thus establishing a stable potential difference on both sides, that namely the Hall voltage.
The experimental results of the Dexinmag series Hall effect test systems are automatically calculated by the software at the same time, such as Bulk Carrier Concentration, Sheet Carrier Concentration, Mobility, Resistivity, Hall Coefficient, Magnetoresistance, and other important parameters.
The Hall effect instrument system consists of an electromagnet, electromagnet power supply, high precision constant current source, high precision voltmeter, Hall effect sample holder, high and low-temperature controller, standard sample, and system software.
