Society is increasingly calling for the incorporation of electronics into more aspects of our daily lives. There is a need for more electronic components in smaller volumes. And their placement is often in unfriendly environments. There is a need to manipulate and modify properties, often on nanometer length scales. In addition, the properties of materials in bulk are often different than those for the same material on surfaces or in nanometer length scale objects. Nanoscale morphology and electronic properties are the focus of this group.
Another method of controlling electronic behavior is the use of new materials, such as organic semiconductors. The use of organic semiconductors is a promising solution to many problems that are not easily solved by traditional silicon devices. Organic materials are usually waxy, or relatively flexible, materials. They can be processed on inexpensive, flexible plastics, are compatible with existing high-throughput roll based printing technologies, and can be made transparent. These attributes make organic semiconductors promising candidates for electronic components such as transistors, diodes, chemical sensors, and large area photovoltaics.
My group is currently involved in UHV-STM, scanning probe microscopy (AFM, C-AFM, TUNA), scanning electron microscopy (SEM), transmission electron microscopy (TEM), Organic Photovoltaics (OPV), chemical sensing, and device characterization.
