Hall Effect Experiment (HEX-21C)
High accuracy and stability, Bench-top form factor, Designed for educational and research use.
The resistivity measurements of semiconductors can not reveal whether one or two types of carriers are present; nor distinguish between them. However, this information can be obtained from Hall coefficient measurements, which are also basic tools for the determination of carrier density and mobilities in conjuction with resistivity measurement. Theory As you are undoubtedly aware, a static magnetic field has no effect on charges unless they are in motion. When the charges ow, a magnetic field directed perpendicular to the direction offlow produces a mutually perpendicular force on the charges. When this happens, electrons and holes will be separated by opposite forces.
