Interplay of Conventional and Spin-Exchange Auger Recombination in Magnetically Doped Quantum Dots
Valerio Pinchetti, Ho Jin, Clément Livache +1
Auger processes play a critical role in the behavior of colloidal quantum dots (QDs). While nonradiative Auger recombination is a key performance-limiting factor in light-emitting…
