Question:

(a) Within the assumptions of the Drude model, calculate the rms velocity of a valence electron in sodium metal at T = 300 K.

(b) Use a quantum-mechanical model to estimate the Fermi velocity of the free carriers (assume m* = me) in Na given that EF = 3.1 eV.

(c) Which velocity estimate is larger?

(d) Do the two models predict different temperature dependences of the free-carrier velocity?
