Time-integrated PL spectra, transient PL, and typical fitting result. Time-integrated PL spectra in the high-density Si ND array with SiC barriers at various temperatures (a). PL time profiles (log-scaled and vertically shifted) of the E1 emission band indicated in (a) from the Si ND array for various temperatures (b). Typical fitting result of the PL time profile at 250 K using a triple exponential function, where the PL time profile is deconvoluted with an instrumental response function (c). A bold black line shows a fitting calculation, and each decaying component resolved is shown by a narrow line.
