Total number of states will not be changed?

  1. Feb 24, 2013 #1
    For bulk solid and superlattices:


    Does the introduction of the periodic potential in superlattices change the total number of states or preserve the same (or almost same) total number of states?

    I dont get you question. Bulk will be made of one material, whereas, supperlattice will have at least two materials. How can you relate states of one with the other?
