Low threshold and efficient multiple exciton generation in halide perovskite nanocrystals

Low threshold and efficient multiple exciton generation in halide perovskite nanocrystals

The hot carriers in halide perovskite nanocrystals cool much slower than those in conventional semiconductor nanocrystals due to the phonon bottleneck. Here, Li et al. demonstrate enhanced multiple exciton generation with lower threshold in intermediate-confined perovskite nanocrystals based on this...
