Nanoelectronic Devices Based on Nanowire Networks
Tech ID: 20296 / UC Case 2004-043-0
UCLA researchers in the Department of Chemistry and Biochemistry have developed a novel technique for synthesizing nanoelectronic devices based on networks of molecular nanowires. Unlike rigid, conventional semiconductors and previous attempts at fabricated nanowires and nanotubes, these networks of nanowires are easily fabricated, chemically tunable, and robust to be integrated with flexible surfaces. In addition to being an attractive alternative to semiconductor processing techniques such as lithography and epitaxy, these nanowire networks have great potential as chemical and biological sensors due to their large surface area and tunable electrical properties.
Electronic devices that use bottom-up synthesized nanoscale materials have been an increasingly attractive alternative to conventional silicon lithographic (top-down) manufacturing, which is complicated, expensive (particularly in capital costs), and prone to defects. Nanomaterials are also robust and able to be integrated onto a variety flexible of substrates. Nanowires in particular are desirable for their quasi-one-dimensional, negligibly resistive conduction path. Recent advances in nanomaterials synthesis have attempted to move beyond epitaxial growth, which can be prohibitively expensive for the increasingly demanding electronics industry. The ability to cheaply and easily produce scalable amounts of nanowires with tunable properties to form flexible networks would be beneficial for a variety of network and sensor applications.
Dr. Richard Kaner has developed a method of epitaxy-free production of flexible nanowire networks that have customizable electrical properties and are more robust than silicon lithography-based systems. Because they can be grown by a myriad of techniques such as solution casting, chemical vapor deposition (CVD), and electrospinning, they can be easily be integrated into a number of device production processes at a much lower cost than both lithography and epitaxy. Additionally, these networks of nanowires are compatible in size with biomolecules, scalable in production, and have a large surface area, making them excellent candidates for highly sensitive sensors.
