Hall Effect, deflection of conduction carriers by an external magnetic field, was discovered in 1879 by Edwin Hall. Also, voltage potential difference between \(A\) and \(B\) (\(V_{AB}\)) can be written as: \[ V_{AB} = \dfrac{R_{H}I_{x}B_{z}}{t} \label{5}\]. It has been known that moving carriers in a magnetic field are accelerated by the Lorentz Force, and the magnitude and the direction of the applied force on the carriers are given as in Equation (1): \[ \mathbf{F} = q\boldsymbol{v}\times \mathbf{B} \label{1}\]. In steady state, current density (net charge flow) along the y-axis has to be zero, which results in Hall coefficient of: (12) R H = p μ h 2 − n μ e 2 q (p μ h + n μ e) 2 Equation (12) indicates that Hall coefficient of a material can either be positive or negative depending on mobility and density of the carriers (electrons and holes). The Hall coefficient, R H, is in units of 10-4 cm 3 /C = 10-10 m 3 /C = 10-12 V.cm/A/Oe = 10-12. ohm.cm/G. systems, at very low temperature and large fields, the Hall resistance show a step-like (rather than linear) dependence on B. The graph was then used to calculate the Hall Coefficient R H using equation (3).

Hall effect is more effective in semiconductor. hall coefficient calculator Determine the hall coefficient for a typical N-type Germanium semiconductor having thickness 0.8mm. The Hall effect is the production of a voltage difference across an electrical conductor, transverse to an electric current in the conductor and to an applied magnetic field perpendicular to the current. 0000001913 00000 n If a current carrying conductor placed in a perpendicular magnetic field, a potential difference will generate in the conductor which is perpendicular to both magnetic field and current.
