Electron's 1-D metallic surface state observed: A step for the prediction of electronic properties of extremely-fine metal nanowires in next-generation semiconductors

Electron's 1-D metallic surface state observed: A step for the prediction of electronic properties of extremely-fine metal nanowires in next-generation semiconductors | Science et Technique | Scoop.it

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.
