Development Stage

Development of technology in various directions, including wiring to electrical circuits

Patent Status

U.S. patent application filed

Market Size

Nanoelectronics market $1.8 billion in 2005, to reach $ 4.2 billion by 2010.

Highlights
  • Gold-tipped nanocrystals – nanodumbells – for nano sized transistors
  • Building blocks for miniature computers, nanosensors  for chemical and biological molecules, and for biomedical applications
  • Prototypes of gold-tipped rods and tetrapods demonstrated in the lab.

Our Innovation

A simple solution, phase reaction for controlled selective growth of gold and other metal tips onto semiconductor rods and tetrapods (structures with four arms or legs).

Key Features

  • Gold tips provide a method for wiring nanocrystals into miniature electronic circuits
  • Provide good electrical contact for speedy and faultless communication channels
  • Tips are natural anchor points to serve as recognition elements for directed self-assembly
  • Self-assembly schemes can be used for the parallel wiring of billions of nanorods onto nano-electronic circuits, vastly increasing computer speed and memory

Development Milestones

  • Expanding method to additional semiconductor materials and metals
  • Investigating approaches for wiring of nanodumbells is in progress

The Opportunity

  • Nanoelectronics includes advanced technology developments, such as molecular electronics, self-assembly using biotechnology, and quantum computing. These developments are expected to emerge in the post-2014 timeframe. These will be ten times more powerful than first generation nanoelectronics, providing a quantum leap in the electronics market over the next 10 years followed by another massive increase in capabilities in the 10 to 20 year horizon.
