← ScienceWhich outcome results when an electron encounters band structure potentials in a crystal lattice?
A)Formation of energy bands instead✓
B)Direct transition into plasmon excitation
C)Complete electron wave function suppression
D)Unrestricted movement follows classical mechanics
💡 Explanation
Energy band formation will occur because electrons undergo Bragg reflection at the lattice planes, inducing quantum interference. Therefore, allowed and forbidden energy ranges arise, impacting electron mobility, rather than free electron motion or total wave function suppression which requires different constraints.
