Electron’s 1-D metallic surface state observed

In the one-dimensional (1-D), various exotic phenomena are predicted that are totally different from those in the 3-D world in which we live. One of the reasons of this is that particles cannot pass each other in 1-D. Researchers have artificially created such unique 1-D nano electronic systems on the surface of a solid, and observed the 1-D electronic state by analyzing photo-emitted electrons from the sample, and verified the electronic structure. —> Read More
