Author Correction: Giant elasto-optic response of gallium selenide on flexible mica

In the original version of the article in Figs. 2, 3 and4 and corresponding text, the value of the strain is estimated for different bending radii, r, of the mica, i.e. the strain is calculated as t/2r, where t = 0.03 mm is the thickness of the mica.For example, for r = 4 cm, t/2r = 0.04%.However, as shown in Fig. 1, the mica is bent to a radius of approximately r = 4 mm, not r = 4 cm.Thus, the actual strain is a factor of 10 higher (0.4%) than that reported in the original manuscript and in the original Figs. 2, 3 and4.The strain is used to calculate and discuss the strain sensitivity of the Raman and photoluminescence spectra (Figs.2,3) and its comparison with the modeling from the literature (Fig. 4).The experimental data on the energy shift of the photoluminescence emission versus the applied strain are now more aligned with the modelling, but reveal a variability amongst different samples that is discussed in terms of the exciton thermalization.The strain is used to calculate and discuss the strain sensitivity of the Raman and photoluminescence spectra (Figs.2,3) and its comparison with the modeling from the literature (Fig. 4).Thus, it is essential to correct the data to ensure the results are accurately presented.
