Equation 3 in the original article is an approximation to the exact formula which appears in ref 52. However, this approximation does not hold for the entire range of energies (specifically, it does not hold for energies below the Fermi energy, which are of negligible importance for the photoluminescence). Equation 3 in the original article should be replaced with the exact expression: f(ϵ; Te;|ÊL|2 = fT(ϵ; Te;)+ δE(ϵ)((1 fT (ϵ; Te))fT (ϵ + ħωL)+ fT (ϵ; Te)(1 fT(ϵ - ħωL)))(3) This correction does not affect any of the equations appearing later in the article nor any other results, discussions, or conclusions reported in the paper. We thank Sebastian Bange for pointing out this mistake to us.
