Si unit of mobility of electron
Did you know?
WebbThe electron mobility, μ, relates the velocity of charged particles in a uniform electric field ( μ = v / E). When these equations are combined, we find: σ = n × e × v / E The numerator is in units of charge per area per unit time (or current density, J), so J = n × e × v, and the denominator is electric field, E. Re-arranging and solving for J: WebbThen the electron mobility μ is defined as v_d = \mu E.. Electron mobility is almost always specified in units of cm 2 /(V⋅s).This is different from the SI unit of mobility, m 2 …
