Heavy hole's and light holes

  1. Mar 26, 2008 #1
    1. The problem statement, all variables and given/known data
    A hole is just a valence band with one missing electron. A semiconductor is just a material that has its conduction electron concentration within a certain range. A direct-gap semiconductor is just a semiconductor with the conduction band edge and the valence band edge on the same vertical in the k-E graph.

    But then my book talks about heavy holes and light holes and split off holes and I just don't understand what they are.


    2. Relevant equations



    3. The attempt at a solution
