← ScienceWhich outcome rapidly emerges when electrons' De Broglie wavelength increases through a quantum dot?
A)Increased quantum tunneling probability✓
B)Enhanced electron-hole recombination
C)Reduced energy level quantization
D)Suppressed Coulomb blockade effect
💡 Explanation
The increased wavelength causes a reduced potential barrier for electrons, hence quantum tunneling probability increases dramatically; because the effective mass decreases, we see quantum tunneling becomes dominant. Therefore, tunneling is prevalent rather than recombination dominating; different potential profiles affect the band structure.
