Spin-orbit coupling in organic semiconductors


Abstract

This project aims at studying the spin-orbit interaction in organic semiconductors, in particular in the device configuration of an organic light-emitting diode, with the goal of developing methods to tune the coupling strength through modifications of molecular structure. Charges in pure hydrocarbon complexes generally experience only very weak spin-orbit coupling, but exhibit spectroscopic signatures of this coupling at high magnetic fields due to small shifts of local g factors.
