Mechanical Manipulation of Quantum Interference in Single-Molecule Junctions.

Mechanosensitive molecular junctions, where conductance is sensitive to an applied stress such as force or displacement, are a class of nanoelectromechanical systems unique for their ability to exploit quantum mechanical phenomena. Most studies so far relied on reconfiguration of the molecule-electrode interface to impart mechanosensitivity, but this approach is limited and, generally, poorly reproducible. Alternatively, devices that exploit conformational flexibility of molecular wires have been recently proposed.

Large Mechanosensitive Thermoelectric Enhancement in Metallo-Organic Magnetic Molecules.

Organic materials are promising candidates for thermoelectric cooling and energy harvesting at room temperature. However, their electrical conductance () and Seebeck coefficient () need to be improved to make them technologically competitive. Therefore, radically new strategies need to be developed to tune their thermoelectric properties.
