... Drude's time it was natural to estimate vo from classical equipartition of energy : mv。2 KBT . Using the known electronic mass , we find a vo of order 107 cm / sec at room tem- perature , and hence a mean free path of 1 to 10 Å . Since ...

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