Nanotubes for Electronics

New method of growing carbon nanotubes to revolutionise electronics. ‘A new method of growing carbon nanotubes is predicted to revolutionise the implementation of nanotechnology and the future of electronics. Researchers at the University of Cambridge have successfully grown nanotubes at a temperature which permits their full integration into present complementary metal-oxide semiconductor (CMOS) technology (350 ºC). Carbon nanotubes are the driving force for current advances in nanotechnology; they have excellent mechanical and electronic properties, the latter making them extremely attractive for new-generation electronics. Increasing efficiency through smaller components is the key towards miniaturisation of technology. The use of carbon nanotubes could find successful use from sophisticated, niche applications to everyday electronics (mobile phones, computers).’

Growing Nanotubes on Silicon a Base for Nanoelectronics. ‘Engineers have developed a technique to grow individual carbon nanotubes vertically on top of a silicon wafer, a step toward using nanotubes to make advanced electronics, wireless devices and sensors by stacking circuits and components in layers.’

Nanotech company sponsors research on flexible electronics. ‘Arrowhead Research Corp., a nanotechnology research company, has announced a deal to sponsor carbon nanotube transistor research by a professor at the physics department at the University of Florida. Arrowhead has agreed to provide $647,000 over a two year period to develop optimized thin-film transistors (TFTs) and prototype TFT arrays as part of a collaboration with Andrew Rinzler to further develop flexible electronic devices made at the University of Florida. In return Arrowhead has been granted the first option to exclusively license and commercialize the technology. TFTs can be used to make products such as RFID tags, flexible displays and electronic paper. In addition, flexible electronics are likely to be produced with low cost ink-jet printing technologies rather than in fabs costing billions of dollars, Arrowhead said.’

Making Nanotube TVs happen. ‘Researchers have turned to carbon nanotubes to create a new class of large area, high resolution, low cost flat panel displays. Some believe field emission display (FED) technology, utilizing carbon nanotubes (CNT) as electron emitter, will be the biggest threat to LCD’s dominance in the panel display arena and that FED is the technology of choice for ultra-high definition, wide-screen televisions. FEDs, in a sense, are a hybrid of CRT televisions and LCD televisions. They capitalise on the well-established cathode-anode-phosphor technology built into full-sized CRTs using this in combination with the dot matrix cellular construction of LCDs. The electron emitters, arranged in a grid, are individually controlled by “cold” cathodes (unlike in normal CRTs, field emission does not rely on heating the cathode to boil off electrons) to generate colored light.’
