IBM Outs Integrated Circuit Smaller Than a Grain of Salt

Graphene's the thinnest electrical material, comprising just a single atomic layer. In addition to its electrical, thermal, mechanical, and optical properties, researchers dig it because it has the potential to be less expensive, more energy-efficient, and more compact than your garden-variety silicon.

So imagine IBM's delight when a team of company researchers built the first circuit that fits all the components, including inductors and a graphene transistor, on a single wafer -- a setup that consumes less space than a grain of salt. The advantage, scientists say, is better performance than what you'd get from a circuit combining a graphene transistor with external components.
