From: Anomalous in-plane anisotropic Raman response of monoclinic semimetal 1 T´-MoTe 2
The density functional calculated band structure of (a) single-layer, (b) bilayer and (c) bulk 1 T´-MoTe2, the band symmetries in the Brillouin zone center Г point are labeled, and A g (A′, A u) and B g (A″, B u) bands are indicated by red and blue labels, respectively. Calculated polarization dependence of the optical transition probability (d) with the maximum a-axis polarization (A g mode) and (e) the maximum b-axis polarization (B g mode). The 0° (90°) corresponds to the a-axis (b-axis) of the 1 T´-MoTe2 sample. (f) Calculated polarization-dependence of the A g and B g phonon mode intensities, from the incident polarization rotation method.
