| Popis: | Great practical needs motivated extensive efforts to discover ultra-low resistance electrical conductors and/or superconductors. Herein we report the observation of a vanishingly small electrical resistance at the ambient temperature and pressure in carbon nanostructured compounds obtained in a hybrid helicon-arc ion-plasma reactor developed by the authors. These findings can originate from resonance-tunneling phenomena that are arising due to nanostructuring in the carbon samples studied. It is argued that in a strongly disordered semiconductor the probability distribution function for the transmission via middle-localized isolated states is bimodal with a significant amount of “open” channels for which the tunneling probability is near unity. |
