Temperature dependences of a FWHM (curve 1), and b PL band maximum Emax (curve 1) measured in the QD sample. The results of fit with the set of parameters Δ = 15 K and Tth = 60 K to Eqs. (1) and (2) are shown by curve 2 in Fig. 3a, 3b. Temperature dependence of InAs energy gap followed the Varshni law [22] is given by curve 3 in Fig. 3b
