The work presented in this thesis focuses on the investigation of two interfaces which play a crucial role in the physics of organic electronic devices: the dielectric/organic semiconductor and the organic semiconductor/metal ones. Regarding the dielectric/OS interface, we have deeply investigated the relationship between the SiO2 cleaning protocol or treatment and the electrical response of OFETs based on two PPV semiconducting polymers (MEH-PPV and OC1C10-PPV) and on a quarterthiopene derivative small molecule (DHCO-4T). Regarding the OS/metal interface, we investigated the electrical performances of PPV and DHCO-4T based OFETs with different metal contacts.

Abstract
The work presented in this thesis focuses on the investigation of two interfaces which play a crucial role in the physics of organic electronic devices: the dielectric/organic semiconductor and the organic semiconductor/metal ones. Regarding the dielectric/OS interface, we have deeply investigated the relationship between the SiO2 cleaning protocol or treatment and the electrical response of OFETs based on two PPV semiconducting polymers (MEH-PPV and OC1C10-PPV) and on a quarterthiopene derivative small molecule (DHCO-4T). Regarding the OS/metal interface, we investigated the electrical performances of PPV and DHCO-4T based OFETs with different metal contacts.
