PL spectra of ex situ annealed sample E7 in N ambient at various temperatures.
PL spectra of in situ annealed samples (a) I6 and (b) I7 in As ambient at various temperatures.
Variation of the PL peak energy as a function of temperature in and quantum wells: reference sample R (a, ▴), ex situ annealed sample E7 (a, ◻), in situ annealed sample I6 (b, •), and in situ annealed sample I7 (b, ◇). The superimposed dotted curves are fits to the Varshni relation.
Variation of full width at half maximum (FWHM) with temperature in samples R (a, ▴), E7 (a, ◻), I6 (b, •), and I7 (b, ◇).
Temperature dependence of the integrated PL intensity for samples R, E7, I6, and I7. The dashed curves are calculated using Eq. (2).
High-resolution x-ray-diffraction spectra (HRXRD) of E7 and I6.
Summary of the samples and their parameters.
