WebJul 16, 2024 · We further evaluate the magnitude of the ph-e interaction by fitting the full width at half maximum (FWHM) of the PL spectrum. The fitted Huang-Rhys factor ( S ) of 4.9 is consistent with reduced electronic dimensionality and increased vibrational degree of freedom, indicating stronger ph- e coupling strength in the Cs 2 Sn I 6 film compared ... WebJul 1, 2024 · Fig. 3 shows the temperature dependence of PL peak energy and FWHM of Al 0.07 Ga 0.22 In 0.71 As QWs with different thermal treatment durations at 170 °C. The PL peak energy was identified by the location of energy corresponding to the maximum of PL emission intensity, not from the line-shape fitting due to the asymmetric spectral line shape.
