Atom writing

This is from an interesting BBC article on the creation of computer chips in Silicon Valley. Click here to read the full article.

“Silicon, with its insulating qualities, has been what computer chips have been etched on since they started.
But silicon is getting leaky and hot as the line widths shrink down to 45 nano- microns, the width of a human hair.
So Intel has tuned to this new base, hafnium, to run cooler and less leaky chips, even though the activity on them is doubling in intensity all the time.
Those new chips aren’t on sale yet, but there’s a ferocious price war going on between Intel and its feisty but small rival, AMD. At the moment, AMD is losing out.
Meanwhile, IBM scientists report they’ve come up with a way of storing information on individual atoms, a deep dive into nanotechnology from the inventors of the scanning tunnelling microscope that makes it possible to “see” at these tiny levels. “

So, we can now write to atoms?

About Author

My name is Michael Sean Gallagher. I am a Lecturer in Digital Education at the Centre for Research in Digital Education at the University of Edinburgh. I am Co-Founder and Director of Panoply Digital, a consultancy dedicated to ICT and mobile for development (M4D); we have worked with USAID, GSMA, UN Habitat, Cambridge University and more on education and development projects. I was a researcher on the Near Futures Teaching project, a project that explores how teaching at The University of Edinburgh unfold over the coming decades, as technology, social trends, patterns of mobility, new methods and new media continue to shift what it means to be at university. Previously, I was the Research Associate on the NERC, ESRC, and AHRC Global Challenges Research Fund sponsored GCRF Research for Emergency Aftershock Forecasting (REAR) project. I was an Assistant Professor at Hankuk University of Foreign Studies (한국외국어대학교) in Seoul, Korea. I have also completed a doctorate at University College London (formerly the independent Institute of Education, University of London) on mobile learning in the humanities in Korea.
