The near-field coupling of nanocrystals (NCs) can be greatly enhanced by fine-tuning the inter-particle distance inside NC superlattices, which show promise for a range of technology applications, such as photovoltaics, light-emitting diodes and thermoelectrics.

Currently, we are employing high pressure processing as a fast and convenient way to precisely tune the inter-NC distance, allowing for a quick optimization of inter-NC distance that represents one ideal confined-but-connected “sweet spot” for NC superlattices to reach the best performance of their desired properties.
