Which outcome initiates when electron energy overcomes the bandgap?

A)Avalanche breakdown within semiconductor material
B)Increased piezoelectricity in crystal lattices
C)Enhanced thermionic emission from surfaces
D)Quantum entanglement between paired electrons

💡 Explanation

Avalanche breakdown begins because impact ionization occurs; free carriers gain enough kinetic energy to excite electron-hole pairs through the bandgap. Therefore, free electrons multiply rapidly, rather than altering piezoelectricity or emitting from the surface under normal conditions.
