Our research effort focuses predominantly on electrical transport in organic thin films and individual molecules.

Organic Semiconductors
Organic semiconductors are an emerging class of electronic materials that offer intriguing prospects for low cost 'plastic electronics'.  Our research focuses on fundamental understanding of the connection between charge transport and structure in these materials such as the relationship between charge carrier mobility, molecular structure, and crystal packing.  We are also interested in the electrical properties of metal-organic contacts and in the synthesis of new organic semiconductor materials.  We study the electrical properties of organic semiconductors via a number of techniques, but most commonly, we build field effect transistors to determine the charge carrier mobilities as a function of temperature and carrier density.

Molecular Electronics and Electrical Transport in Molecules
"Molecular electronics" refers to an emerging technology and scientific research area in which the electrical transport properties of molecules are utilized for some function, e.g., electrical switching or sensing.  Key challenges for molecular electronics are the discovery of reproducible and robust methods for electrically addressing individual molecules and the elucidation of the connection between molecular structure and charge transport properties.  To make contact to molecules and to test their electrical properties, our research group fabricates metal-molecule-metal junctions using conducting probe atomic force microscopy.  We are examining the properties of these junctions as a function of molecular length, functional group distributions, bonding and the chemical nature of the metal-molecule contact.
