Which risk increases when a quantum dot's radius approaches exciton Bohr radius?

A)Auger recombination becomes more likely✓

B)Thermal conductivity dramatically decreases

C)Phonon scattering approaches zero intensity

D)Dielectric constant becomes severely nonlinear

💡 Explanation

Auger recombination increases when near the exciton Bohr radius because quantum confinement increases electron-hole wave function overlap. The confined carriers are more likely to interact non-radiatively via Auger Recombination; therefore Auger recombination increases, rather than changes in thermal, intensity or constitutive properties.
