← ScienceWhich consequence results when electron wave functions in a semiconductor device become unconfined?
A)Increased quantum mechanical tunneling occurs✓
B)Decreased carrier mobility predominates strongly
C)Electrical breakdown becomes less probable
D)Phonon scattering rises significantly faster
💡 Explanation
Increased quantum mechanical tunneling occurs because wave functions extending beyond confinement lead to a higher probability of tunneling through potential barriers. Therefore, tunneling increases, rather than something else, because electrons encounter barriers more frequently.
