Query: Shot noise in diffusive conductors: A quantitative analysis of
  electron-phonon interaction effects   Using the 'drift-diffusion-Langevin' equation, we have quantitatively
analyzed the effects of electron energy relaxation via their interaction with
phonons, generally in presence of electron-electron interaction, on shot noise
in diffusive conductors. We have found that the noise power $ S_I(\omega )$
(both at low and high observation frequencies $\omega $) drops to half of its
'mesoscopic' value only at $\beta \gtrsim 100,$ where $\beta $ is the ratio of
the sample length $L$ to the energy relaxation length $l_{% {\rm ph}}$ (the
latter may be much larger then the dephasing length). It means in particular
that at low temperatures the shot noise may be substantial even when $L\sim
10^{-2}$ -- $10^{-1}$ cm, and the conductor is 'macroscopic' in any other
respect.
