Abstract
Correction for ‘The polarization-dependent anisotropic Raman response of few-layer and bulk WTe2 under different excitation wavelengths’ by Qingjun Song et al., RSC Adv., 2016, 6, 103830–103837.
In part (d) of Fig. 4 of the original manuscript, and in the description of part (d) in the Fig. 4 caption, the wrong labels were given for the modes. The labels “Bg” and “Au” should be “Bu” and “Ag”, respectively. The corrected Fig. 4 and its caption are shown below:
 | ||
| Fig. 4 (a–c) The calculated band structures of monolayer, bilayer and bulk WTe2, respectively. The representative band symmetries at Γ point are labelled, and the insets are their 2D Brillouin zones. Calculated polarization dependence of the optical transition probability (d) from the Bu to Ag (Elas ≈ 1.5 eV) and (e) from the Ag to Au (Elas ≈ 2.3 eV) in monolayer WTe2, as indicated in (a). 0° corresponds to the W–W chain (a-axis) direction, the initial incident polarization and scattered polarization are along the a-axis (θ0 = 0°). (f) The representative calculated polarization dependent intensities of Ag and Bg modes in monolayer WTe2 with certain θ0 (∼15°). | ||
Additionally, in the Results and Discussion section, in the text below Fig. 4, two sentences should be revised as follows:
“For Elas ≈ 2.3 eV, the excited electron will transit from the Ag valence band to Au conductance band, and the corresponding polar plot is shown in Fig. 4(e), where the maximum (minimum) absorption corresponds to the perpendicular (parallel) relation between the incident polarization and a-axis”.
“To study the influence of electron–photon interaction on the anisotropic Raman scattering, we first assume the electron–phonon interaction (He–ph) in the Raman scattering is not polarization dependent”.
The Royal Society of Chemistry apologises for these errors and any consequent inconvenience to authors and readers.
