Charge transfer integral
WebWe present a multiscale framework for charge carrier mobilities in organic thin films empowered by machine-learned charge transfer integrals. The choice of the molecular representation is crucial for accurate and sensitive predictions. WebIn general, insulators can be divided into Mott–Hubbard insulators and charge-transfer insulators . A Mott–Hubbard insulator can be described as. This can be seen as …

WebJun 1, 2024 · The charge transfer integral is significantly influenced by the stacking method and relative orientation of the molecules. The transfer integrals for both holes and electrons are calculated using the site-energy correction method [35]. The larger charge transfer integral, the faster the charge-carrier transfer rate. WebCharge transfer integrals for hole transport can be calculated from the energetic splitting of the two highest-occupied molecular orbitals (HOMO and HOMO-1) in a system consisting of two adjacent molecules, also called “energy splitting in dimer” (ESID) method. For electron transport these can be calculated from the two lowest-unoccupied ...
