Light-Emitting Molecular Junctions

Chromophoric molecules can be used as efficient light emitters, and their properties are efficiently exploited in OLED technology. Shrinking such devices at the single-entity level would yield massive information on the fundamental chemistry and physics of light-emission, and quantum phenomena could be exploited to achieve single-photon emission (a discrete flux of photons, all identical and well-spaced in time), important for fields such as optical computing and quantum cryptography.

Multimetallic and Cluster-containing Molecular Wires

Polyatomic clusters, either purely metallic, oxide based or binary semiconducting, have great promise in nanoelectronics due to their properties, intermediate between single atom and bulk solids. Using techniques adapted from more traditional molecular electronics, it is possible to trap a single cluster in a junction, and study its properties in a well-defined and reproducible geometry. The wide range of nuclearity, stoichiometric composition, molecular geometry and choice of ligands offered by cluster chemistry opens up a vast chemical space that can be explored to optimise the performances of single-entity devices.

Scaling-Up Molecular Electronics

All the information on the electrical and quantum mechanical behaviour of molecules obtained at the single-molecule level can be efficiently adapted to larger area devices, which have the advantages of a more straightforward fabrication and more tolerance to fabrication defects. It is now possible to working with several different techniques, from soft fabrication techniques to the use of liquid metal electrodes, to study and develop 2-dimensional molecular devices based on monolayer technology, with the final aim of integrating these in current semiconductor devices.
