Shubnikov-de Haas oscillations from topological surface states of metallic Bi${}_2$Se${}_{2.1}$Te${}_{0.9}$

Keshav Shrestha, Vera Marinova, Bernd Lorenz +1

We have studied the quantum oscillations in the conductivity of metallic, p-type Bi${}_2$Se${}_{2.1}$Te${}_{0.9}$. The dependence of the oscillations on the angle of the magnetic field w…
