McGill physicists find a new state of matter in a 'transistor': Could previously unknown type of electron crystal help the future of electronics?

McGill University researchers have discovered a new state of matter, a quasi-three- dimensional electron crystal, in a material very much like those used in the fabrication of modern transistors. This discovery could have momentous implications for the development of new electronic devices. Currently, the number of transistors that can be inexpensively crammed onto a single computer chip increases exponentially, doubling approximately every two years, a trend known as Moore's Law. But there are limits, experts say. As chips get smaller and smaller, scientists expect that the bizarre laws and behaviours of quantum physics will take over, making ever-smaller chips impossible.

Storing bits of memory in nanotube switches

The world of computer memory has been approaching an interesting crossroads. Most people are aware that we are rapidly approaching fundamental limits with both magnetic storage mediums like the hard drive, and in the fabrication of transistors through photolithography, which yields RAM and flash memory. Several areas of research, including fields like phase change memory, may provide the opportunity to move away from both magnetic domains and transistors. To explore a different route to future memory systems, researchers went high-tech and put multiwalled carbon nanotubes (MWCNTs) to use—only to discover that they work through a surprisingly retro mechanism.

Directed Growth of Carbon Nanotubes Across Gaps

An experiment has shown that when single- walled carbon nanotubes (SWNTs) are grown by chemical vapor deposition in the presence of an electric field of suitable strength, the nanotubes become aligned along the electric field. In an important class of contemplated applications, one would exploit this finding in fabricating nanotube transistors; one would grow SWNTs across gaps between electrodes that would serve, subsequently, as source and drain contacts during operation of the transistors.

IQE provides epitaxy for US graphene project

Epitaxy foundry IQE has joined a new research project that is aiming to develop high-speed transistors based on carbon atom monolayers.

Self-Assembling Chips First Step Towards Extra-Bendy Evil Robots

It may look all innocent, but this little logic circuit is made from organic molecules that lined themselves up to form 300 transistors, without the need for machine production. This kind of chip-in-a-test-tube approach to creating semiconductors, demonstrated as effective for the first time by Philips Research, could cause a big leap towards cheaper, more flexible electronics—in a word, to quote The Graduate, "plastics."

Welcome to the Future: In Search of a Legal Moore's Law

In 1965, Gordon Moore, then the Chairman of Intel, observed that every 18 months or so Intel and other semiconductor companies had managed to put roughly twice as many transistors on a chip. That annual boost both accelerated chip performance--improving existing applications and enabling new ones--and required ongoing improvements in chip design and manufacturing.

The long road towards single molecule nanotechnology electronics

(Nanowerk Spotlight) Using single molecules as electronic components is the ultimate goal for future electronic nanotechnology devices (see for instance our Spotlight "Using quantum mechanics to turn molecules into transistors"). In order to explore the electronic properties of a single molecule, researchers have to make electrical contact between electrodes and molecules – and this has proven to be a big challenge. The problem is forming stable and reproducible molecular bridges and determining their electrical properties. It has already been shown that molecular bridges can be formed. However, their mechanical stability and reproducibility is usually low.

New State of Matter Could Extend Moore's Law

rennerik writes "Scientists at McGill University in Montreal say they've discovered a new state of matter that could help extend Moore's Law and allow for the fabrication of more tightly packed transistors, or a new kind of transistor altogether. The researchers call the new state of matter 'a quasi-three-dimensional electron crystal.' It was discovered using a device cooled to a temperature about 100 times colder than intergalactic space, following the application of the most powerful continuous magnetic field on Earth."

Strong elasticity size effects in ZnO nanowires

Recently, zinc oxide (ZnO) nanowires have drawn major interest because of their semiconducting nature and unique optical and piezoelectric properties. Various applications for ZnO nanowires have been conceived, including the next generation of field effect transistors, light emitting diodes, sensors and resonators. ZnO nanowires are also envisioned as nanogenerators by exploiting the coupling of semiconducting and piezoelectric properties.

Atom expulsion shapes nanodevices

Nanodevices can be shaped using a highly focused electron beam. So say researchers at the University of Illinois at Urbana Champaign in the US who have developed a technique called electron-beam expulsion of atoms (EBESA) to etch nanoholes as small as 2.5 nm across in multiwalled carbon nanotubes and niobium nanowires. If improved, the method might be used make single-electron and field-effect transistors, photon and chemical detectors and even superconducting-based solid-state qubits.

Repairing Genetic Mutations With Lasers?

Roland Piquepaille writes "German researchers at the Christian-Albrechts-Universität zu Kiel (CAU) think they've proved that genetic information can be controlled by light. The group studied the interaction between the four DNA bases — adenine (A), cytosine (C), guanine (G), and thymine (T) — by using femtosecond time-resolved fluorescence spectroscopy. The researchers think that they've demonstrated that DNA strands differ in their light sensitivity depending on their base sequences. The team thinks that it might be possible in the future to repair gene mutations using laser radiation. One of the project leaders said that 'it might even be possible under some circumstances to make transistors from DNA that would work through the hydrogen bonds.

Panasonic and Renesas Technology to Collaborate on Development of SoCs at 32-nm Process Node

Panasonic Corporation and Renesas Technology Corp. are now collaborating on the development of elemental process technologies for SoCs of the 32-nm node. The two companies are confident that their 32-nm node transistor technology and other advances can soon be applied to products in mass production. The 32-nm SoC process employs a developed transistor technology with a metal/high-k1 gate stack structure and interconnect technology, using a low-k2 material. To achieve a device using complementary metal-insulator semiconductor (CMIS)3 technology, a type of complementary Metal Oxide Semiconductor (CMOS), at a 32-nm node, an ultrathin film cap layer4 is applied at the atomic level to transistors with a metal/high-k gate stack structure under optimized conditions.
