Fermi level tuning of Ag-doped Bi(2)Se(3) topological insulator
The temperature dependence of the resistivity (ρ) of Ag-doped Bi(2)Se(3) (Ag(x)Bi(2−x)Se(3)) shows insulating behavior above 35 K, but below 35 K, ρ suddenly decreases with decreasing temperature, in contrast to the metallic behavior for non-doped Bi(2)Se(3) at 1.5–300 K. This significant change in...
