Carbon nanotubes push the limit of flexible electronics

Over the past decades, the aggressive scaling of transistors made on rigid silicon wafers has steadily boosted the performance of personal electronics and supercomputers. For emerging applications like real-time analytics and Internet of Things (IoT), high-performance logic circuits and sensors made on flexible or unconventional substrates are needed in order to enable the true computation […]

Recent papers detail carbon nanotube scalabilty, integration breakthroughs

Carbon nanotubes (CNT) appeal to the semiconductor industry because they’re superior electrical conductors compared to silicon with a mere 1 nanometer body thickness. So why don’t we have CNT chips in everything from mainframes to mobile devices, yet? Scalability of the transistor and large-scale integration are still big challenges. But two papers my colleagues and […]

Another kind of chip with carbon nanotubes

This is the second of a four-part series about IBM featured papers at IEDM 2016. The annual International Electron Devices Meeting is “the world’s pre-eminent forum for reporting technological breakthroughs in the areas of semiconductor and electronic device technology, design, manufacturing, physics, and modeling.” So IBM researchers brought their scanning probe thermometer, their air spacer for […]

Welding at an atomic level

As part of our IBM Research Q&A series we sat down with Shu-Jen Han to talk about carbon nanotubes and reducing resistance down to 9nm. How are silicon and carbon similar when it comes to transistors? Let’s start with carbon because it has so many different allotropes, from carbon nanotubes, graphene to diamonds. But diamonds, […]
