Abstract:
This work is located at the frontier between molecular electronics and spintronics. In this framework, self-assembled monolayers (SAMs) of photo-switchable compounds have been grafted on ferromagnetic surfaces (FMs). Molecular junctions integrating these molecules are expected to exhibit two distinct states of resistance associated to each isomer.
By using FM electrodes, the realization of photo-switchable magnetic molecular tunnel junctions could lead to the development of novel devices based on the interplay between spin-polarized currents and molecular photo-switching. Despite promising theoretical results, to the best of our knowledge, no experimental works have ever been realized.
Therefore, we focus on experimental studies of molecular photo-switching on FM-SAM/metal junctions toward the realization of hybrid molecular opto-spintronics devices.
