Hall effect in Semiconductor materials

When a magnetic field is applied perpendicular to the direction of flow of charge carriers, in a semiconductor material, charge carriers experience a force in transverse to the direction of applied magnetic field and carriers flow. This effect is known as Hall effect. Being very simple and straight forward phenomena in physics, Hall effect is a fundamental principle in magnetic field sensing and have many practical applications in our daily life. This demonstration shows Hall effect in semiconductor materials and shows how n-type and p-type semiconductors can be identified.
