Spin-orbit coupling in organic semiconductors (B03)

• Subject Area: Experimental Condensed Matter Physics
• Term: since 2017
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 314695032

Electronic spins in organic semiconductors are only minimally perturbed by spin-orbit interactions, their g-factors being almost identical to that of a free electron. The g-factor can be measured accurately under magnetic resonance, but the resolution of the experiment is limited by the strong hyperfine coupling arising from the abundant hydrogen atoms. A high-frequency magnetic resonance technique will be developed, operating close to THz frequencies, to overcome disorder broadening by hyperfine fields and resolve shifts in the g-factor due to the subtle spin-orbit coupling.
