Chemical complementarity in the contacts for nanoscale organic field-effect transistors.
This study describes the effect of covalent derivatization of source and drain electrodes with monolayers of organic semiconductors. These monolayers form a template on the metal surface and provide better electronic coupling between the electrode and the semiconductor. We see a large improvement in nanoscale (40-100 nm) transistors only when the monolayer presents functionality that is complementary to the chemical and electronic structure of the molecular semiconductor.
