Theory of hall effect

Webb23 sep. 2024 · The Hall effect (named after Edwin H. Hall in 1879) is the tendency for electrons to move to one edge of a level conductor in a transverse magnetic field. This … WebbTherefore, for the simple explanation of a moderate magnetic field, the following is the Hall coefficient: R H = p μ H 2 − n μ e 2 e ( p μ H + n μ e) ∴ R H = ( p − n b 2) e ( p + n b) 2. Where, b = μ e μ H. n is electron concentration. p is hole concentration. 𝛍 e is the mobility of electron. 𝛍 H is the mobility of the hole.

Webb12 sep. 2024 · However, Hall potentials indicate that for a few metals, such as tungsten, beryllium, and many semiconductors, the majority of charge carriers are positive. It turns out that conduction by positive charge is caused by the migration of missing electron sites (called holes) on ions. Conduction by holes is studied later in Condensed Matter Physics.
