Organic thin film transistors (OTFTs) based on have attracted a great deal of attention as they are the critical components to fabricate low cost and large area flexible displays and sensors for future application in organic electronics technology. However, the major problem to use organic thin film transistor in logic circuits is the high operating voltage required. Researchers in India believe this problem can be solved by using organic materials with high dielectric constant as gate dielectrics.

A potential solution to overcoming the fundamental scaling limits of silicon-based electronic circuitry is the use of a single molecular layer that self-organizes between two electrodes: so-called molecular electronics. Nature itself is highly efficient in using self-organized structures for electronic transport (photosynthesis in plants, nerve cells, etc.), and now similar self-organization of organic molecules is used to make electronic devices. Electric transport through single molecules has been studied extensively by both academic and industrial research groups. It has been demonstrated that the size of a diode, an element used in electronic circuitry, can be reduced reproducibly below 1.5 nm. Transport data, however, typically differ by many orders of magnitude and the fabrication hurdle is reliability and yield. Researchers in The Netherlands now have demonstrated a technology to manufacture reproducible molecular diodes with high yields (>95 %) with unprecedented lateral dimensions.

A new methodology for integrating nanowires with micropatterned substrates using directed assembly and nanoscale soldering was developed by researchers at Johns Hopkins University in Baltimore. This overcomes the difficulty in making electrical contacts to nanoparticles, which so far has been a major limitation to fabricating integrated nanoelectronic devices containing large numbers of nanoparticles.
