Low temperature PL emission spectra of InAsN and InAs reference samples grown on GaAs (001).
Temperature dependence of the PL spectrum for sample A0299 (1% N). The inset shows the semilog plot of the PL spectra. For clarity, the PL spectra in the inset are displaced along the vertical axis.
PL spectrum at for A0299 containing 1% N. The line is an exponential fit to the high energy tail of the PL spectrum. The inset shows the PL spectra at different after subtraction of an exponential fit to the high energy side of the PL emission.
-dependence of the PL peak energy for A0299 containing 1% N. The continuous line is the calculated -dependence of the band gap energy according to the empirical Varshni equation.
