← ScienceWhich risk increases when a high-powered laser induces multiphoton absorption in a quantum dot crystal?
A)Carrier escape from quantum confinement✓
B)Increased phonon-mediated energy transfer
C)Enhanced radiative recombination efficiency
D)Reduced Auger recombination probability
💡 Explanation
Carrier escape risk increases because multiphoton absorption allows electrons to overcome the quantum confinement potential via Quantum Tunneling, therefore allowing them to leave the dot, rather than remaining localized to create excitons.
