Problem

A metal has one electron band with density ne=1.0×1028 m−3n_e = 1.0\times10^{28}\,\mathrm{m^{-3}} and one hole band with density nh=3.0×1028 m−3n_h = 3.0\times10^{28}\,\mathrm{m^{-3}}. Calculate the Hall coefficient in the high-field limit ωcτ≫1\omega_c\tau\gg1 for both bands, taking e=1.602×10−19 Ce=1.602\times10^{-19}\,\mathrm{C}.
