A Year Ago : Chips The Size Of Atoms
News The remaining hydrogen atom was left bouncing between the silicon atoms. The atom-sized computer chip has been built, claimed scientists at the Danish University of Techology, reducing the 'on-off' element of a microchip to atomic dimensions.

Chips The Size Of Atoms
News The remaining hydrogen atom was left bouncing between the silicon atoms. The Danish team reckons it has a device in which a single atom can jump back and forth to create the 'on' and 'off' states of a computer, leap-frogging technologies like that...

A Year Ago: Scientists Move Closer To Quantum Computing
News Colorado institute increases control over atoms Boffins at the NIST have succeeded in moving atoms into and out of quantum states with far more precision than has been achieved in the past. Scientists at National Institute of Standards and...

Scientists 'teleport' Atomic Particles
News Teleportation -- "sending" atoms, or at least their properties, through space without any physical movement -- is possible, according to scientists at the National Institute for Standards and Technologies.

IBM Focuses On Microscopic Advances
News With a new electron microscope from IBM and Nion, semiconductor researchers can not only examine individual atoms, they can also look at the spaces between them. When we had a layer of insulation that was 100 atoms thick, it didn't really matter if...

British Scientists Create Atom-thick Transistor
News British scientists have created what they claim is the world's smallest transistor, measuring one atom in thickness and 10 atoms in width. Graphene is a one-atom-thick lattice of carbon atoms, organised in a honeycomb or chickenwire formation.

Intel Unveils New Chip Manufacturing Technology
News Intel will increase the performance of its microprocessors next year, in part by spreading out its silicon atoms. The Santa Clara, California-based chipmaker will use "strained silicon" -- or silicon where the atoms in the chip's silicon base are...

Nanoparticle Research Blows Open New Possibilities
News With regular bulk materials, only the top layer of atoms participates in a reaction. The San Diego-based start-up has created a manufacturing process for producing small, stable metallic particles that consist of only a few atoms.

Silicon's Successor Lurks In The Lab
News Nanotubes "heal" themselves by shifting to replace atoms that get removed. A carbon nanotube is essentially a sheet of carbon atoms -- arranged in hexagons -- that curls up into a tube. In a relatively short time, carbon nanotubes -- thin tubes of...

Tiny Tubes Mean Big Chip Advances
News IBM believes that nanotubes, which measure five atoms to ten atoms wide and are 10,000 times narrower than a human hair, are the most promising replacement material for silicon to develop advanced chips in the coming decades.

Intel To Serve Up Metal Chips
News Currently, the gate, which controls whether a transistor is on or off, is made of silicon atoms while the gate dielectric, an insulating layer below the gate, is made of silicon dioxide. The gate dielectric on chips coming out of Intel’s fabs next...

Intel Spices Up Silicon For Ultrafast Future
News We've now got layers only four or five atoms thick, and we can't scale past three, two, one, zero. Strained silicon improves this by moving the atoms farther apart. At the Intel Developer Forum in San Francisco on Thursday, Intel's director of...

Strained Silicon Speeds AMD's Chips
News Strained silicon is a design technique in which silicon atoms are forcibly pulled apart from each other. With the atoms spaced out further from one other, electrons can move more rapidly, similar to how a hockey puck can zip faster across a rink...
