Using scanning tunneling microscopes (STMs) made in house, we assemble and study circuits formed by a single organic molecule chemically bond to two metallic electrodes. We work mainly in ambient conditions, and explore the electrical properties of these molecular circuits, including their thermopower, this is the electrical voltage created between the extremes of the molecule under a thermal gradient.
More specifically, we study:
Electrical properties of organic molecule families: oligo(phenyl ethynylene)s,oligoynes, phthalocyanines, porphyrins... (JACS 2013, JACS 2014, JACS 2015...)
Thermo power of single-molecule junctions: we explore to ability to a single molecule of different compounds to generate an electrical potential when they are under a thermal gradient (Nano Lett. 2013, Nature Mater. 2016, Chem. Soc. Rev. 2016).
Key factors involved in the formation and stability of molecular junctions (J. Chem. Phys. C 2013, J. Am. Soc. 2013, Chem. Soc. Rev. 2015...).
Fullerene-based molecular junctions (Nano Lett. 2011, JOC 2014).
Graphene as electrode for molecular electronics.
