IRG-4 research enables novel technological advances in the area of hybrid organic/inorganic nanoelectronic materials by improving fundamental understanding and optimizing processing efficiency across multiple length-scales. The IRG's collaborative efforts take advantage of several unique and complementary strengths:
- Synthesis: organic high-k dielectrics and inorganic semiconductor nanowires.
- Processing: single-walled carbon nanotube sorting and printable electronics.
- Characterization: scanning probe microscopy and synchrotron x-ray techniques.
- Theory: non-equilibrium transport and quantum electronic structure.
As an example, self-assembled nano-dielectrics (SANDS) are being used to dramatically improve thin film transistors made from organic, nanotube, and nanowire active layers.
