20. Expression (19), when rewritten as (formula presented), with (formula presented) and (formula presented) coincides with Eq. (2) given by Naveh et al. (Ref. 14).
21. The disappearance of the factor (formula presented) in Eq. (20) leads to a remarkable difference between the multichannel 3D case and a one-channel case studied earlier (Ref. 5). In a 1D conductor the noise comes from a narrow energy range of order (formula presented) at the Fermi level, while in a 3D conductor the main contribution to the noise comes from the lowest longitudinal energies far below the Fermi energy, where more transversal states within the range (formula presented) near the Fermi sphere are available [see also discussion of Fig. 22(a)].

23. Note that in all the asymptotic formulas, for both the current and noise, the bias U may be replaced by the more exact (formula presented) Because of our assumption (formula presented), we neglect (formula presented) This correction may improve, however, the results at intermediate biases when the barrier is not sufficiently small.
