Exciton-Trion Conversion Dynamics in a Single Molecule

2022-04-05T17:41:09+02:00Tags: , , , |

Authors: Dolezal, Jiri; Canola, Sofia; Merino, Pablo; Svec, Martin Journal: ACS NANO Publication date: 2021/04/27 DOI: 10.1021/acsnano.1c01318 Abstract: Charged optical excitations (trions) generated by charge carrier injection are crucial for emerging optoelectronic technologies as they can be produced and manipulated by electric fields. Trions and neutral excitons can be efficiently induced in single molecules by [...]
