Question:
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.)

As I'm a Ph.D. student, so I'm more focussed on my chemistry laboratory. I have qualified two national level exams viz, GATE, and NET JRF (Rank 68). So I'm highly qualified in chemistry subject. Also, I have two years of teaching experience in this subject, which includes college teacher as well as a personal tutor. I can assure you if you hire me on this particular subject, you are never going to regret it.
Best Regards.
