Transiently delocalized states enhance hole mobility in organic molecular semiconductors

Nature Materials, Published online: 14 September 2023; doi:10.1038/s41563-023-01664-4

Dynamic disorder reduces the carrier mobility in organic semiconductors (OSs) to an extent that depends on their specific electronic band structure. Here the authors study the temperature-dependent hole mobility of two structurally similar OSs and find that thermal access to transiently delocalized states enhances hole mobility in C8-DNTT-C8 compared to DNTT.Nature Materials, Published online: 14 September 2023; doi:10.1038/s41563-023-01664-4Dynamic disorder reduces the carrier mobility in organic semiconductors (OSs) to an extent that depends on their specific electronic band structure.
