University of Kentucky researchers have discovered a means of reducing gate leakage current of transistors in computer chips that will permit chip producers to continue developing more efficient and powerful chips with reduced power consumption.
Zhi Chen, associate professor of electrical and computer engineering, found that applying rapid thermal processing directly on gate insulators – used to control current flow of transistors in computer chips – can dramatically reduce the chips leakage current and correspondingly the power consumption. In fact, the technique can improve the insulating qualities of gate insulators so that their direct tunneling current is reduced by 10,000 to 100,000 times. No effect was found if rapid thermal processing was not directly applied on the gate insulators.
In order to improve computer chips performance, transistors size and gate insulators have to be continuously shrunken so that more components can be packed into a single chip. Computer chip producers were hitting a wall in downscaling the transistors and gate insulators because of their inability to reduce the leakage current of the existing gate insulators. This new technique will help the chip producers to develop more powerful chips with low-power consumption.

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
