Multifunctional surfaces structured with electroactive and magnetic molecules for electronic and spintronic devices (ELECTROMAGIC)
Start date: Jun 1, 2012, End date: May 31, 2015 PROJECT  FINISHED 

"ELECTROMAGIC is embedded in the field of molecular electronics which has gained much attention during the last decade. The current limitations of the silicon based technology for the fabrication of electronic devices able to fulfil the actual demand, i.e., speed, miniaturization, low cost and flexibility among others has drawn the attention of the scientific community. The use of functional molecules appeared as a very attractive alternative. The current goal is to develop new molecular systems and immobilize them on surfaces to obtain real devices based on the molecular intrinsic properties leading to specific functions such as memories, switches, sensors, etc. The main aim in ELECTROMAGIC is to functionalize surfaces structured with self-assembled monolayer (SAMs) with TTFs and PTMs that are multifunctional (electroactive and magnetic) systems. TTF radical cation and PTM radical forms are highly persistent and have a spin moment. Using these molecules it is possible to obtain surfaces with an electroactive function with optical and magnetic properties that can be easily and reversible tuned. The possibility of performing a partial oxidation of the molecules forming the SAM would permit the electronic transport within the layer itself. Thanks to the opposite electroactive properties of TTFs and PTM, the preparation of mixed SAMs would lead to multifunctional 3-state switch devices. This project addresses some of the main barriers in molecular electronics which in many occasions are limiting the possible future integration of the molecules into real devices, such us the stability of the different states of the molecules (stability of the ON and OFF state of the memory device), the easy access to these different states and, finally the long-term stability. A big effort will be devoted to the use of PTM radicals SAMs as platforms for spintronic devices. The possible polarization of the spin during the transport could be used to store information."
