It was recently shown that molecular wires can mediate long-range, phase-coherent tunnelling with remarkably low attenuation beyond a few nanometres, even at room temperature. This creates the possibility of using quantum interference (QI) to control the transport of electrons, spins, and phonons through nanoscale junctions for a wide range of applications such as molecular switches, sensors, piezoelectricity, thermoelectricity, and thermal management. In this talk, I will discuss evidence of room-temperature QI in molecular junctions [1] and strategies to control QI for molecular electronic applications [2].
