Hall Effect (HALL) Testing is a sophisticated analytical technique widely utilized in material science and semiconductor research. It is particularly instrumental in characterizing the electrical properties of materials, including semiconductors, metals, and thin films. The method involves applying a magnetic field perpendicular to the flow of electric current through a sample, resulting in a transverse voltage known as the Hall voltage. This voltage provides critical insights into the behavior of charge carriers within the material, enabling the determination of key parameters such as carrier type, carrier concentration, and mobility.
The Hall Effect is fundamentally based on the Lorentz force, which acts on charge carriers moving through a magnetic field. When an electric current is passed through a material placed in a perpendicular magnetic field, the charge carriers experience a force that deflects them, creating a voltage across the material. This transverse voltage, known as the Hall voltage, is directly proportional to the magnetic field strength, the current, and the charge carrier density. The Hall coefficient, derived from the Hall voltage, can be used to determine the type of charge carriers (electrons or holes) and their concentration. Additionally, carrier mobility can be calculated by combining the Hall coefficient with resistivity measurements.
