Graphene Lithography - Etching with Atomic Precision


Kat Arney

Chris Smith
Zinc metal, applied in patterns to multilayer graphene, can selectively remove only one layer of the graphene.

This week, a new discovery suggesting that the chemistry of life could have come to Earth in a meteorite, how foetal immunity protects the expectant mother, and why we need to be careful with stem cells - a new study has found that they have an above average chance of carrying cancer-causing genetic changes.  Plus, a new technique to etch graphene sheets with single-atom precision.

Key component of life's building blocks could have come from space

The origins of life on earth are a hotly debated topic among scientists. One theory suggests that meteorites brought some of the chemical building blocks for amino acids – the molecules that make up proteins. Now tests on a meteorite provide more evidence that they might have kickstarted the chain o...

Graphene Lithography - Atomic Precision Etching

Researchers at Rice university have developed a new way to etch structures into stacked piles of graphene, the marvellous material consisting of a single layer of carbon atoms. This could allow manufacturers to make computer chips from graphene in much the same way they currently do for silicon......
