Scholarcy highlights

  • A new method of developing an "effective-mass" equation for electrons moving in a perturbed periodic structure is discussed
  • The resulting theory generalizes the usual effective-mass treatment to the case where a band minimum is not at the center of the Brillouin zone, and to the case where the band is degenerate. The latter is striking, the usual Wannier equation being replaced by a set of coupled differential equations
