← ScienceWhich outcome occurs when the potential energy periodicity is weakly perturbed?
A)Miniband formation in the band structure✓
B)Complete suppression of Bloch oscillations
C)Drude model becomes completely accurate
D)Umklapp scattering becomes practically forbidden
💡 Explanation
Miniband formation occurs due to weak perturbations introducing new periodicities (superlattices; weak additional periodic potentials): Bloch's theorem causes band structure distortions. Therefore, minibands form rather than complete suppression or increased validity of Drude models, because potential energy periodicity is perturbed not eliminated.
