Monolayer to Multilayers Nanostructural Evolution in N type Oligothiphenes: Implications for OFET Performance

, ,

Keywords: , ,

This study elucidates the nature of the interface between the organic semiconductor and source-drain electrodes in OFET devices. The pitted and disordered monolayer results in poor mobilities for bottom contact OFETs. Reorientation of the molecules in multilayers by 90° results in efficient stacking and overlap of pi orbitals with an associated increase in top contact OFET mobility by three orders of magnitude.
