... Drude's time it was natural to estimate vo from classical equipartition of energy : mv2 = kÅT . Using the known electronic mass , we find a v 。 of order 107 cm / sec at room tem- perature , and hence a mean free path of 1 to 10 Å ...

... Drude model this leads to good order of magnitude agreement with the Wiedemann - Franz law , but also predicts a contribution to the specific heat of a metal of 3k , per electron that was not observed.2 This paradox cast a shadow over ...

... Drude by a factor of order kÅT / EF ; the correct estimate of v2 is not the classical thermal mean square velocity of order k , T / m , but vp2 = 28F / m , which is larger than the classical value by a factor of order & F / kg T ...
