Gate-tuned quantum oscillations of topological surface states in β-Ag(2)Te
We report the strong experimental evidence of the existence of topological surface states with large electric field tunability and mobility in β-Ag(2)Te. Pronounced 2D Shubnikov-de Haas oscillations have been observed in β-Ag(2)Te nanoplates. A Berry phase is determined to be near π using the Landau...
