Abstract
Spin degeneracy in conjugated polymers will be destroyed in the presence of magnetic field because of the existence of Zeeman splitting. The characteristic of carriers in polythiophene is studied in the framework of a tight binding model. It is found that spin polarons can be created preferentially in energy when electrons are doped under a reasonable magnetic field considering the influence of electron–electron interactions and electron–phonon coupling, which is favorable for spin polarized transport in organic semiconductors and is of great importance in the field of organic spintronics.
