Correlating nanomorphology with charge-transport anisotropy in conjugated-polymer thin films |
2009/9/8 |
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. The research was conducted at the NSRRC beamline BL17B1. Y. F. Huang , C. W. Chang, D.
