Which consequence results when a quantum dot's wavefunction energy functions deviate significantly from parabolicity?

A)Increased electron-hole recombination times result

B)Phonon scattering rates increase dramatically

C)Auger recombination processes become dominant✓

D)Exciton binding energies become minimal

💡 Explanation

Auger recombination dominates, because non-parabolicity modifies the electron and hole density of states, enhancing the overlap of their wavefunctions driving the non-radiative transitions that define Auger recombination; therefore efficiency decreases, rather than being dictated predominantly by phonon mechanisms in simpler systems.
