Author(s): Y. Huang, H. P. Wang, R. Y. Chen, X. Zhang, P. Zheng, Y. G. Shi, and N. L. Wang We report an optical spectroscopy study on single crystals of Na2Ti2As2O, a sister compound of the superconductor BaTi2Sb2O. The study unexpectedly reveals two density wave phase transitions. The first transition, at 320 K, results in the formation of a large energy gap and removes the majority of t... [Phys. Rev. B 89, 155120] Published Mon Apr 14, 2014
