IBM Reports Carbon Nanotube Transistor Breakthrough

Oct 1, 2015 |

Perhaps Moore’s law isn’t doomed just yet. Maybe. IBM Research (NYSE: IBM) reported in a paper in Science today a technique for making carbon nanotube transistors with tiny (~9nm) contacts that exhibit low, size-independent resistance. This overcomes a huge hurdle in shrinking transistor size beyond current limits. “I think this is the first carbon nanotube Read more…

Stanford Group Creates Four-Layer Stacked Chip

Dec 18, 2014 |

With transistor scaling slated to come up against some fundamental limits over the next five to seven years, chip designers are hot on the trail of technologies to extend the exponential advances described by Moore’s law. One of the most promising areas of R&D involves stacking layers of logic and memory into 3D chips. The implementation Read more…

IBM Bets on Nanotubes to Succeed Silicon in 2020

Jul 2, 2014 |

The effect of five decades of exponential progress with silicon chips doubling in speed every couple years as observed by Intel cofounder Gordon Moore in 1965 cannot be overstated. As silicon-based transistors push against the limits of physics, the death of Moore’s law could pack a devastating blow to the industry and even the global Read more…

Carbon Nanotubes Pitched as Post-Silicon Contender

Jun 23, 2014 |

With TOP500 list stagnation likely signaling the slow-down of an exponential known as Moore’s law, what better time to consider alternatives to silicon-based microelectronics. Researchers from the USC Viterbi School of Engineering point to carbon nanotubes as a promising replacement for silicon as the traditional transistor material. The advantage of carbon nanotubes is that they are Read more…

Carbon Nanotubes Aid Microprocessor Cooling

Jan 23, 2014 |

The semiconductor industry is facing several hurdles in developing the next generation of microprocessors. As more and more transistors are squeezed onto a chip, overheating threatens to negate performance gains. Countering this is a two-step process that begins with getting the heat out of the chip and onto the circuit board, where it can then Read more…

Stanford Debuts First Carbon Nanotube Computer

Sep 27, 2013 |

A new computer made of carbon nanotubes, created by a team of Stanford engineers, may be the first serious silicon challenger.
