Author(s): D. Chen, T.-T. Zhang, Z.-D. Song, H. Li, W.-L. Zhang, T. Qian, J.-L. Luo, Y.-G. Shi, Z. Fang, P. Richard, and H. Ding We performed a Raman scattering study of Na 2 Ti 2 As 2 O . We identified a symmetry breaking structural transition at around T s = 150 K, which matches a large bump in the electrical resistivity. Several new peaks are detected below that transition. Combined with first-principles calculations, our polarizati… [Phys. Rev. B 93, 140501(R)] Published Mon Apr 04, 2016
