Anisotropic mobility in spin-coated MEH-PPV films is due to an interfacial layer of several nanometers at the film-substrate interface with a higher electron density assisted by local chain alignment parallel to the substrate. This layer is formed via spin-coating. The strength of this interface effect is dependent on the solvent used.
