(A) obtain the photon emission rate R(E) for a direct gap transition of na LED considering the joint density of states and the probability of occupancy of states in the bands .
R(E)\propto (E-Eg)^{1/2}exp(-E/KT)
(B) show that the maximum will occur at E=Eg+1/2KT
(C) Show that the full width at half maximum(FWHM) of the LED
emission spectrum is = 1.8
(D) plot schematically the photon emission rate as a function of
energy.
