Start date: May 7, 2013,
End date: May 6, 2015
"MULTITUDES is aimed at providing multidisciplinary and multisectorial training and mobility to a very promising researcher in order to further his career development so that he may become an independent and leading scientist either in the university or private sector. The researcher will receive training in an emerging field at the interface between Physics Materials-/Nano-/Supramolecular -Science and Electrical Engineering. The research program in MULTITUDES aims to develop both asymmetrically functionalised electrodes and multifunctional devices for organic electronics. This will be achieved by modifying adjacent metal (nano)electrodes with different self-assembled monolayers (SAMs) through a process of chemisorption and selective electrochemical desorption, and will include in this some SAMs that have properties sensitive to light or that can be switched electrochemically to confer additional functionality to the surface and ultimately to the device.Within this framework, MULTITUDES aims to:- Characterise competitive adsorption processes between SAM molecules, and build a library of competitive adsorption/desorption processes between candidate molecules.- Develop protocols for fabrication of asymmetric planar electrodes by adsorption and selective electrochemical desorption of SAM molecules.- Improve control of charge injection into organic field-effect transistors (OFETs) by incorporation of asymmetric SAM functionalised electrodes.- Map the local electrical characteristics of planar OFET devices incorporating asymmetric electrodes whilst under bias using scanning probe techniques in order to improve understanding of the physico-chemical properties ruling operation with a nanoscale spatial resolution.- Fabricate novel devices for application as sensors or as multifunctional logic gates whose properties can be switched between two states through interaction of an external (non-electrical) stimulus with the SAM functionalised electrode."
