• Kronig-Penney model with the tail-cancellation method 

    Mishra, Subodha, 1965-; Satpathy, Sashi Sekhar, 1956- (American Association of Physics Teachers, 2001)
    The Kronig-Penney model of an electron moving in a periodic potential is solved by the so-called tail-cancellation method. The problem also serves as a simple illustration of the tail-cancellation method itself.
  • The quantum mechanics of electric conduction in crystals 

    Olsen, Raina J.; Vignale, Giovanni, 1957- (American Association of Physics Teachers, 2010)
    We introduce a model of electrons incident on a one-dimensional periodic potential and show that conduction is a result of the interference of different parts of an electron wave that bounce multiple times through a series ...
