What’s the smoothest known material?

And it isn't James Brown.

Asked by: Jack Catalano, USA

In 2011 a team of physicists in Spain created a perfectly smooth material by coating a thin silicon crystal with a layer of lead a dozen or so atoms thick.

According to the team, quantum forces between the atoms levelled out even atom-sized bumps. The result was a surface known as a quantum-stabilised atom mirror, which will be used in new-generation microscopes.
