Demonstrating breakneck signal speed of 10 gigahertz, method uses nanotubes instead of conventional copper wires
UC Irvine scientists in The Henry Samueli School of Engineering have demonstrated for the first time that carbon nanotubes can route electrical signals on a chip faster than traditional copper or aluminum wires, at speeds of up to 10 GHz. The breakthrough could lead to faster and more efficient computers, and improved wireless network and cellular phone systems, adding to the growing enthusiasm about nanotechnology’s revolutionary potential.
“Our prior research showed that nanotube transistors can operate at extremely high frequencies, but the connections between the transistors were made out of somewhat slower copper, thus forming a bottleneck for the electrical signals,” said Peter Burke, assistant professor of electrical engineering and computer science, and one of the researchers who developed the technology. “In this technology we show that nanotubes can also quickly route electronic signals from one transistor to another, thus removing the bottleneck.”

Team develops fast, cheap method to make supercapacitor electrodes

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.
To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
