← ScienceWhich outcome occurs when wave functions of two quantum dots overlap substantially in a semiconductor device?
A)Quantum tunneling between dots enhances✓
B)Phonon scattering rate decreases sharply
C)Electron-hole recombination is completely suppressed
D)Dielectric breakdown strength substantially increases
💡 Explanation
When wave functions overlap, quantum tunneling occurs because electrons can pass through the potential barrier via quantum mechanical probability, leading to enhanced tunneling. Therefore tunneling is enhanced across dots, rather than phononic decrease, recombination reduction, or dielectric increase which require different physical phenomena.
