Relativistic electric potential near a resting straight carbon nanotube of a finite-length with stationary current

Based on the Lienard – Wiechert potentials for a uniformly and rectilinearly moving electron, relativistic electric field is studied near densely filled with potassium atoms single-walled carbon nanotube (K@CNT) stationary current inside it. The in laboratory coordinate system arises (due to Lorentz transformations) only of finite length. This result summation Coulomb fields positively charged ionic cores an equal number ballistically valence electrons that create current. It shown magnitude negative potential K@CNT direction perpendicular does not depend density. relationship obtained between radius open channels ballistic electron transfer over atoms. Landauer formula used, which relates quasi-one-dimensional direct electrical conduction. For first time, analytical formulas are dependence voltage ends its limit zero absolute temperature. case considered when distance from point registration above center much less than diameter 2 nm length 100 mm, under external strength 5 mV/mm, about mV. Modern measurement techniques make it possible register predicted potential.
