Abstract

The magnetoelectronic transport in molecular ensembles is intrinsically related to a series of carrier-molecule quantum interactions, resulting in embracing physical and chemical phenomena. Its understanding has paved the way for the development of novel device concepts, such as organic transistors, organic light-emitting diodes, and biosensors. For all of these applications, nanoscale molecular ensembles and nanomaterials commonly play a needful role. In this scenario, this project proposes to investigate the properties of magnetoelectronic transport in molecular junctions connected by nanomembranes as a road to the development of spin valves and nanoscale sensors. The proposal ranges from the junctions' integrative manufacturing, to applications on the development of hybrid nanodevices based on both ultrathin (< 10 nm) molecular structures and metal nanomembranes.
