Epitaxial Dimers and Auger-Assisted Detrapping in PbS Quantum Dot Solids

We explore the dynamic interaction of charge carriers between band-edge states and sub-band trap states in PbS quantum dot (QD) solids using time-resolved spectroscopy. In monodisperse arrays of 4- to 5-nm diameter PbS QDs, we observe an optically active trap state ∼100–200 meV below the band edge t...
