Abstract
We study theoretically electronic transport through a contact of a quantum wire with 2D or 3D leads and find that if the contact is not smooth and adiabatic then the conduction is strongly suppressed below a threshold voltage VT, while above VT the dc current Ī is accompanied by coherent oscillations of frequency f = Ī/e. The effect is related to interelectronic repulsion and interaction of dc current with the Friedel oscillations near a sharp contact. In short conducting channels of length L < L0 ≅ ℏVF/eVT and at high temperatures T > T0 ≅ eVT/kB the effect is destroyed by fluctuations.
