Question:

Barriers in series and Ohm's Law

(a) Derive (36) from (35).

(b) Show that the 1D Drude conductivity σ_1D, = n_1D^e2τ/m can be written as σ_1D = (2e²/h)ℓ_B. (The momentum relaxation rate and the backscattering rates are related as 1/τ = 2/τ_B, because the former corresponds to the relaxation from p to 0 while the latter corresponds to relaxation from p to – p.)
