|Abstract:||We report measurements of the surface Shubnikov-de Haas oscillations (SdH) on crystals of the topological insulator Bi2Te2Se. In crystals with large bulk resistivity (similar to 4 Omega cm at 4 K), we observe similar to 15 surface SdH oscillations (to the n = 1 Landau level) in magnetic fields B up to 45 T. Extrapolating to the limit 1/B -> 0, we confirm the 1/2-shift expected from a Dirac spectrum. The results are consistent with a very small surface Lande g factor.|
