Temperature Dependence of Exciton Diffusion in a Small‐Molecule Organic Semiconductor Processed With and Without Additive. (16th March 2015) - Lin, Jason D. A.
Abstract The temperature dependence of exciton diffusion in a small‐molecule organic semiconductor processed with and without additive is investigated. As‐cast and 1, 8‐diiodooctane‐processed films yield exciton diffusion lengths of 6.8 and 4.9 nm, respectively. Using a Monte Carlo simulation, it is shown that processing with 1, 8‐diiodooctane increases the excitonic trap density, which directly reduces the exciton diffusion length.
