Research Interests

At the level of fundamental science, it was demonstrated recently that molecular wires can mediate long-range phase-coherent tunnelling with remarkably low attenuation over distances of few nanometer, even at room temperature. This creates the possibility of using quantum and phonon interference to engineer electron and phonon transports for a wide range of applications such as molecular switches, sensors, thermoelectricity and thermal management. To understand transport properties of such devices, it is crucial to calculate their electronic and phononic transmission coefficients. Our aim is to study transport properties of nanoscale junctions for various applications such as molecular electronic building blocks, sensors, molecular spintronic, thermoelectric, piezoelectric and optoelectronic devices.
