Derivation of hall effect
Weby is the electric field, called the Hall field, in the y direction and B z the magnetic field in the z direction. In an experiment, we measure the potential difference across the sample—the Hall voltage V H— which is related to the Hall field by V H = − Z w 0 E ydy = −E yw . (4) Thus, from equations (1), (3) and (4) we obtain V H ... Webeffect is known as the Hall effect, and is the basis of many practical applications and devices such as magnetic field measurements, and position and motion detectors. With …

Quantum Hall e ect is a quantum mechanical general-ization of the classical Hall e ect, which is observed for two-dimensional systems at very low temperatures. Quantum Hall e ect is a relativity new discovered phenom-ena and one of the most interesting phenomena within condensed matter physics.
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… WebThis is called the Hall Voltage, VH. The positive and negative charges drift to opposite ends of the conductor producing a hall voltage when a magnetic field is applied. An equation …
