Multi-scale modeling of spin transport in organic semiconductors — •Amaury Souza1, Shayan Hemmatiyan1, Erik Mcnellis1, Denis Andrienko2, and Jairo Sinova1 — 1Johannez Gutenberg Universy - Mainz — 2Max Planck Institute for Polymers - Mainz
In this work, we present our theoretical framework to simulate simultaneously spin and charge transport in amorphous organic semiconductors. By combining several techniques e.g. molecular dynamics, density functional theory and kinetic Monte Carlo, we are be able to study spin transport in the presence of anisotropy, thermal effects, magnetic and electric field effects in a realistic morphologies of amorphous organic systems. We apply our multi-scale approach to investigate the spin transport in amorphous Alq3 (Tris(8-hydroxyquinolinato)aluminum) and address the underlying spin relaxation mechanism in this system as a function of temperature, bias voltage, magnetic field and sample thickness.
