Infrared Photodetectors: Rapid In Situ Ligand‐Exchange Process Used to Prepare 3D PbSe Nanocrystal Superlattice Infrared Photodetectors (Small 25/2021)

Abstract

A new strategy for retaining long‐range order during ligand exchange of nanocrystal superlattices is used to construct PbSe infrared photodetectors by Christine Orme and co‐workers (article number 2101166). The ordered photodetectors have a 16× higher responsivity and 2× faster response time compared to disordered ones.
