Hall effect - semiclassical approach

  1. Feb 17, 2006 #1
    I'm perplexed by semiclassical treatment of Hall effect.
    I'm refering to Aschroft Mermin text. At page 233 is my doubt:
    why is it necessary the introduction of w drift velocity vector and why does it take that form? :uhh:

    Recall the trajectory of a free charged particle in crossed E and B fields (from Jackson, or some SR course) - it is a cycloid with a drift velocity along E X B.

    You can derive this by transforming to the frame where E' = 0.
