Mobility of electrons

  1. Mar 2, 2008 #1
    why the mobility of electrons more than holes despite the fact that electrons have larger effective mass than holes.

    What system are you talking about? In Si and GaAs, the (transport) effective mass of electrons is smaller than that of holes.

    Note: In general, the transport effective mass will differ from the DOS effective mass, particularly if the valley degeneracy is not 1 or if there is a large anisotropy in the structure.

    I am talking about DOS effective mass.....

    did anyone ever answer this question about the http://www.3gcgroup.com/" [Broken] of the electrons?

    Don't the electrons have to move in order for holes to move? How else do you get holes?

    Please pay attention to the dates of the posts, your last post was in a 6 year old thread, this one is 4 years old.
