Azároff introduces the nearly-free electron model using a brilliant analogy: consider electrons in a periodic potential like marbles rolling over a corrugated surface. Energy gaps arise when the marble’s wavelength matches the corrugation spacing. He then derives the band gap without heavy quantum mechanics, using only the Bragg condition.
