Research Interests

Size and shape tunable periodic structures derived from functional block copolymers
Using controlled free-radical polymerization techniques, we are making model block copolymers of varying chemical functionalities. Characteristic of the polymerization techniques used, these block copolymers are narrow in molecular weight distributions. Depending on the details of the synthesis parameters – composition, monomer type, etc. – these block copolymers spontaneously microphase separate to form periodic nanostructures. Current research efforts in this area focus on fluorinated block copolymers and environmentally-responsive block copolymers.

Solution-processable organic conductors and semiconductors for thin-film electronics
The ability to replace thermally-evaporated metal and organic semiconductors with solution-processable counterparts as active device components will lower capital and operational costs associated with thin-film electronics fabrication. We are examining the processing-structure-property relationships of these materials to assess their viability. Current research efforts in this area focus on water-dispersible, conductive polyaniline and several p-type solution-processable anthradithiophenes.

Soft lithography and novel patterning schemes for plastic electronics
The chemical- and mechanical fragility of organic semiconductors calls for the development of non-invasive patterning technologies for establishing efficient electrical contact. Our group has developed nanotransfer printing (nTP) and stamp-and-spin-cast as means to fabricate functional organic thin-film devices. Research in this area continues to explore elastomeric-stamp-based patterning schemes for creating high-resolution functional features on rigid and flexible substrates over large areas.

Self-assembled monolayer as electrically-active components in nanoscale electronics
We are interested in understanding the assembly of conjugated molecules on metal and semiconductor surfaces, and how the molecular orientation and structure can influence the macroscopic electrical characteristics. High-resolution spectroscopic techniques, including transmission and reflectance infra-red spectroscopy and synchrotron-based near-edge X-ray absorption fine structure spectroscopy are used to elucidate the ensemble-averaged structure and orientation of the molecular assembly. Our work currently focuses on conjugated dithiols on gold and gallium arsenide surfaces.
