Inelastic tunneling of electrons can generate the emission of photons withenergies intuitively limited by the applied bias voltage. However, experimentsindicate that more complex processes involving the interaction of electronswith plasmon polaritons lead to photon emission with overbias energies. Werecently proposed a model of this observation in Phys. Rev. Lett. \textbf{113},066801 (2014), in analogy to the dynamical Coulomb blockade, originallydeveloped for treating the electromagnetic environment in mesoscopic circuits.This model describes the correlated tunneling of two electrons interacting witha local plasmon-polariton mode, represented by a resonant circuit, and showsthat the overbias emission is due to the non-Gaussian fluctuations. Here weextend our model to study the overbias emission at finite temperature. We findthat the thermal smearing strongly masks the overbias emission. Hence, thedetection of the correlated tunneling processes requires temperatures $k_BT$much lower than the bias energy $eV$ and the plasmon energy $\hbar\omega_0$, acondition which is fortunately realized experimentally.
