The Hall effect is the deflection of electrons (holes) in an n-type (p-type) semiconductor with current flowing perpendicular to a magnetic field. The deflection of these charged carriers sets up a voltage, called the Hall voltage, whose polarity depends on the effective charge of the carrier.
The Hall Effect Coefficient is a parameter that is experimentally determined to be negative and independent of the Seebeck coefficient. It is challenging to measure due to the very low mobilities of free carriers.
The Hall effect is the production of a potential difference (the Hall voltage) across an electrical conductor that is transverse to an electric current in the conductor and to an applied magnetic field perpendicular to the current.
15 kwi 2010 · The basic physical principle underlying the Hall effect is the Lorentz force, which is a combination of two separate forces: the electric force and the magnetic force. When an electron moves along the electric field direction perpendicular to an applied magnetic field, it experiences a magnetic force - q v X B acting normal to both directions.
The principle of the Hall effect states that when a current-carrying conductor or a semiconductor is introduced to a perpendicular magnetic field, a voltage can be measured at the right angle to the current path. This effect of obtaining a measurable voltage is known as the Hall effect.
The Quantum Hall Effect refers to the phenomena exhibited by 2D materials, such as graphene, where electrons under a low temperature and magnetic field follow quantized cyclotron orbits leading to a quantization of electrical resistance.
