|Title:||A Generalized Roosbroeck-schockley Relation For Iii-nitrides In Far-from-equilibrium Conditions|
Da Costa A.P.
|Abstract:||We consider the behavior of the absorption coefficient and luminescence spectrum in the steady state when III-nitrides semiconductors (compounds GaN, AlN, and InN) are in far-from-equilibrium conditions created by an electric field. We analyze the high frequency part of the spectra obtaining a generalization of the Roosbroeck-Schockley relation, Λ RS(ω, E f), the ratio between the frequency dependent luminescence I(ω) and the absorption coefficient α(ω), for nonequilibrium conditions which are dependent on the electric field intensity E F. We show that the carrier's temperature within a small error is proportional to |d In[Λ RS(ω, E F)]/dω|.|
