We report a numerical study of the effect of interface alloying and band alignment on the Auger
recombination processes of core/shell nanocrystals. Smooth interfaces are found to suppress Auger
recombination, the strength of the suppression being very sensitive to the core size. The use of
type-II structures constitutes an additional source of suppression, especially when the shell confines
electrons rather than holes. We show that “magic” sizes leading to negligible Auger recombination
[Cragg and Efros, Nano Letters 10, 313 (2010)] should be easier to realize experimentally in
nanocrystals with extended interface alloying and wide bandgap [-]
