Large Gap Topological Insulator Bi2Te3 with a Single Dirac Cone on the Surface

Y. L. Chen, J. G. Analytis, J. H. Chu +11

We investigate the surface state of Bi${}_2$Te${}_3$ using angle resolved photoemission spectroscopy (ARPES) and transport measurements. By scanning over the entire Brillouin zone (BZ)…
