Inorganic semiconductors in nanoscale structural forms - ribbons, wires, platelets, disks, etc. - represent enabling materials for high performance, mechanically flexible electronic circuits that can be fabricated on lightweight, plastic substrates. Many believe that these types of systems, which can cover large areas, will be important for new applications in consumer electronics. This talk describes aspects of soft lithographic type printing approaches that can be used to form these systems, was well as the underlying surface chemistry and physics that governs their operation. Mechanically flexible and stretchable, circuits, solar cells and emissive displays will be discussed.
