Temperature dependence of the inelastic scattering time τε in metallic n-GaAs (n=ND−NA=7.83×1016 cm−3) is determined experimentally in the wide temperature range of 50 mK–8 K by two methods: One is from the H2 [H: magnetic field] dependence of the magnetoconductivity Δσ in weak fields, where Δσ=σ(H, T)−σ(0, T) is proportional to τε3⁄2H2 [T: temperature]. The other is from the temperature dependence of Δσ in strong fields, which is given by Δσ=(e2⁄2π2h)[0.605(eH⁄ch)1⁄2−(Dτε)−1⁄2], where D is the diffusion constant. We find that the two methods give the T−1 temperature dependence of τε. This result is in agreement with the recent theory of τε∝T−1 in 3-dimensional system calculated by Isawa.
