 Molecular Electronics Local Probes of Nanoscale Systems Chemical and Biological Sensing Nanotube and Nanowire Electronics


Quantum Transport in Nanoscale Systems
Our group is interested in the nanometer-scale transport properties (charge, energy, spin, ...) of molecular and super-molecular systems. 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 optical lithography, electron beam lithography, thin film deposition and etching approaches. Much of our work relies on facilities in the University of Pennsylvania Micro/NanoFabrication Laboratory. Once we have a molecular circuit, we measure its properties using a variety of techniques including: low-temperature magnetotransport, thermal conductivity measurement, and hybrid scanning probe techniques that let us measure local electronic properties with nanometer-scale resolution.
