Physicists play the nanopipe

Electrons caught making waves in carbon nanotubes.

Eight years ago, researchers at IBM's research laboratories in California took us to the shores of the quantum world using a special microscope to reveal waves in the electron sea that washes over the surface of copper.

The same technique has now captured electron waves reverberating down the world's smallest organ pipe: a tube of pure carbon several atoms' width across1.
