Barriers In Series And Ohms Law A Derive 36 From 35

Barriers in series and Ohm’s Law 

(a) Derive (36) from (35). 

(b) Show that the 1D Drude conductivity σ1D, = n1De2τ/m can be written as σ1D = (2e2/h)ℓB. (The momentum relaxation rate and the backscattering rates are related as 1/τ = 2/τB, because the former corresponds to the relaxation from p to 0 while the latter corresponds to relaxation from p to – p.)
