Characterization of Few-Layer 1T′ MoTe(2) by Polarization-Resolved Second Harmonic Generation and Raman Scattering

We study the crystal symmetry of few-layer 1T′ MoTe(2) using the polarization dependence of the second harmonic generation (SHG) and Raman scattering. Bulk 1T′ MoTe(2) is known to be inversion symmetric; however, we find that the inversion symmetry is broken for finite crystals with even numbers of...
