New spintronics material could help usher in next generation of microelectronics

  • PDF
TechAndComputer (Mar. 24, 2010) — As the electronics industry works toward developing smaller and more compact devices, the need to create new types of scaled-down semiconductors that are more efficient and use less power has become essential.

In a study to be published in the April issue of Nature Materials (currently available online), researchers from UCLA's Henry Samueli School of Engineering and Applied Science describe the creation of a new...

Boost for technology: Huge step toward mass production of coveted form of carbon

  • PDF
TechAndComputer (Mar. 11, 2010) — Scientists have leaped over a major hurdle in efforts to begin commercial production of a form of carbon that could rival silicon in its potential for revolutionizing electronics devices ranging from supercomputers to cell phones. Called graphene, the material consists of a layer of graphite 50,000 times thinner than a human hair with unique electronic properties. Their study appears in ACS' Nano Letters.

New graphene 'nanomesh' could change the future of electronics

  • PDF
TechAndComputer (Feb. 28, 2010) — Graphene, a one-atom-thick layer of a carbon lattice with a honeycomb structure, has great potential for use in radios, computers, phones and other electronic devices. But applications have been stymied because the semi-metallic graphene, which has a zero band gap, does not function effectively as a semiconductor to amplify or switch electronic signals.

While cutting graphene sheets into nanoscale ribbons can...

Electrons on the brink: Fractal patterns may be key to semiconductor magnetism

  • PDF
TechAndComputer (Feb. 10, 2010) — Just as the heartbeats of today's electronic devices depend on the ability to switch the flow of electricity in semiconductors on and off with lightning speed, the viability of the "spintronic" devices of the future -- technologies that manipulate both the flow and magnetic "spin" of electrons -- will require similarly precise control over semiconductor magnetism.

Achievement of this goal necessitates a detailed...

Quantum computing leap forward: altering a lone electron without disturbing its neighbors

  • PDF
TechAndComputer (Feb. 6, 2010) — A major hurdle in the ambitious quest to design and construct a radically new kind of quantum computer has been finding a way to manipulate the single electrons that very likely will constitute the new machines' processing components or "qubits."

Princeton University's Jason Petta has discovered how to do just that -- demonstrating a method that alters the properties of a lone electron without disturbing the...
