Another 2D perovskite study led by @YBoeije this time in @J_A_C_S on tuning inorganic-organic electronic coupling for enhanced interlayer exciton transport.
Work with Linn Leppert (@UTwente), Wouter Van Gompel (@uhasselt), Akshay Rao (@DeptofPhysics), & others.
(Pyr-C₂)₂PbI₄ and (Pyr-C₄)₂PbI₄ are structurally very similar hybrid semiconductors, but optically very different.
Our new paper, just published in JACS, explores why:

Check out this new work in @acsnano led by @StranksLab PhD candidate @YBoeije in collaboration w/ Akshay Rao’s group @DeptofPhysics
The study elucidates important exciton-phonon interactions and exciton trapping dynamics in WS2 TMD monolayers.
See more: pubs.acs.org/doi/10.1021/acs…
Excitons in monolayer WS₂ can trap at defects without losing vibrational coherence, presenting new ways of thinking about how excitons interact with defects in 2D materials, with implications for quantum information technologies.

ALT A schematic of an “edge dislocation.” The orange balls represent a perfect crystal, but there is an extra column of purple balls which interrupt the structure. This extra column causes the parts of the crystal close to the dislocation (a few tens of nanometres away) to become deformed (strained). The pink region denotes the highly strained core of the dislocation. Adapted from Orr, K. W. P. et al., Adv. Mater. 35, 2305549 (2023) DOI: 10.1002/adma.202305549
