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 theangle of the magnetic field with the surface as well as the Berry phasedetermined from the Landau level fan plot indicate that the observedoscillations arise from surface carriers with the characteristic Diracdispersion. Several quantities characterizing the surface conduction arecalculated employing the Lifshitz-Kosevich theory. The low value of the Fermienergy with respect to the Dirac point is consistent with the metalliccharacter of the bulk hole carriers. We conclude that, due to the peculiarshape of the valence band, the Shubnikov-de Haas oscillations of the bulkcarriers are shifted to higher magnetic fields which allows for the detectionof the quantum oscillations from the topological surface states at lower field.
