We investigate the effect of electron-phonon inelastic scattering on shotnoise in nanoscale junctions in the regime of quasi-ballistic transport. Wepredict that when the local temperature of the junction is larger than itslowest vibrational mode energy $eV_c$, the inelastic contribution to shot noise(conductance) increases (decreases) with bias as $V$ ($\sqrt{V}$). Thecorresponding Fano factor thus increases as $\sqrt{V}$. We also show that theinelastic contribution to the Fano factor saturates with increasing thermalcurrent exchanged between the junction and the bulk electrodes to a valuewhich, for $V>>V_c$, is independent of bias. A measurement of shot noise maythus provide information about the local temperature and heat dissipation innanoscale conductors.Comment: 4 pages, 2 figure
