Bistable Nano-Objects on Surfaces (BINOS)
Date du début: 1 sept. 2012, Date de fin: 31 août 2015 PROJET  TERMINÉ 

Coordination networks are molecular systems that show various physical properties (magnetic, electrical, optical, etc.). Some networks have the particularity to have bistable states, which are interesting towards the development of memories, switches or sensors. The study of the evolution of their properties at the nanometer scale let us foresee the development of miniaturized systems that can be included in more complex devices.The objective of this project is to develop synthesis tools of bistable coordination nanosystems on inorganic surfaces. We plan to use simple techniques of surface chemistry that do not require expensive facilities. In a second time, we will characterize the physical properties of these systems and we will determine the specific effects of the size reduction to the nanometer scale. We will use very sensitive techniques, adapted to systems with few materials, for which the weakness of the signals is often a critical element. Finally, we will use these techniques to address the systems in a controlled manner. Indeed, in order to develop memory devices, it is necessary to write and read the information independently. We also plan to perform measurements in environmental conditions with the purpose of elaborating sensors.
