About Us

Our group’s interests include transport phenomena (charge, energy, and spin) in nanoscale systems, including carbon nanotubes, graphene, transition metal dichalcogenides, and hybrid nano-structures based on these materials conjugated with proteins, synthetic peptides, and DNA. These systems are of rising interest both from the technological (possible future nanoelectronics!) and fundamental points of view. In order to study the electronic properties, we must first connect nanometer size objects to the outside world. To this end, we use a variety of nanofabrication techniques including photolithography, electron beam lithography, thin film deposition and etching approaches. Much of our work relies on facilities in the University of Pennsylvania Singh Center for Nanotechnology. Once we have a molecular circuit, we measure its properties using a variety of techniques including low-temperature magneto-transport, thermal conductivity measurement, and hybrid scanning probe techniques, that let us measure local electronic properties with nanometer-scale resolution.
