TL;DR: It is found that the exciton diffusion length, which exceeds 30 nm in some cases, can be tuned by adjusting the inorganic shell thickness and organic ligand length, offering a powerful strategy for controlling exciton movement.

TL;DR: This work reports the first realization of high thermal conductivity in the thin film of a conjugated polymer, poly(3-hexylthiophene), via bottom-up oxidative chemical vapor deposition (oCVD), taking advantage of both strong C=C covalent bonding along the extended polymer chain and strong π-π stacking noncovalent interactions between chains.

TL;DR: In this article, the authors present a framework for analyzing transient photoluminescence interfacial quenching experiments to extract exciton diffusivity and diffusion length, and demonstrate the utility of their model by applying it to a colloidal quantum dot (QD) thin film interface found in a recently reported record-efficiency QD light-emitting device.

TL;DR: It is found that homogeneously broadened PbS quantum dot arrays can be realized if quantum dot batches are sufficiently monodisperse, and structural disorder has a greater impact than energetic disorder in inhibiting charge carrier transport.

TL;DR: In this paper, 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 was explored.
