Hetero-integrated Nanostructures and Nanodevices

News from 2016

  • An international team led by researchers at UCLA and Caltech has demonstrated how altering the form of platinum nanoscale wires from a smooth surface to a jagged one could dramatically reduce the amount of precious metal used as catalysts in fuel cells and lower the cost.

  • Researchers at UCLA’s California NanoSystems Institute have developed a dramatically advanced tool for analyzing how chemicals called nanocatalysts convert chemical reactions into electricity. Current spectroscopy methods require large laboratory machines to measure chemical reactions, but the new technique uses a nanoelectronic chip to do the same thing while the reactions are taking place — which previously was very difficult — with better accuracy, and while gathering a completely new set of data.

  • Researchers at the University of California, Los Angeles, have succeeded in minimizing both the contact resistance and channel length in transistors made from the 2D semiconductor molybdenum disulphide, so making a device that has a high ON current of 0.83 mA/µm at 300K. This new work shows for the first time that 2D semiconducting transistors can compete with silicon-based ones in terms of performance – as defined by the International Technology Roadmap for Semiconductors (ITRS).
