← ScienceWhich outcome occurs when electron energy matches band gaps?
A)Material becomes more electrically insulating✓
B)Increased quantum tunneling probability emerges
C)Material exhibits strong diamagnetic behaviour
D)Thermal conductivity approaches zero kelvin
💡 Explanation
The material becomes more insulating when the electron energy matches the **band gap**. Electrons cannot propagate because significant energy is required to jump the forbidden gap. Therefore, electrical conductivity drops, rather than increasing via tunneling or magnetic behavior.
