Carrier Mobility in Topological Insulators In addition to an energy gap, which is a characteristic of all band insulators, the electronic structure of the recently discovered three-dimensional topological insulators Bi2Te3 and Bi2Se3 contains a surface state with a Dirac-like dispersion. This state is predicted to be associated with high carrier mobility. However, the transport properties of the surface state are obscured by the bulk material and challenging to measure. Qu et al.

Weak Anti-localization and Quantum Oscillations of Surface States in Topological Insulator Bi2Se2Te
It is demonstrated that Bi2Se2Te can serve as a suitable topological insulator candidate for achieving intrinsic quantum transport of surface Dirac fermions and weak anti-localization and quantum oscillations originated from surface states in Bi2 Se2Te crystals.
Emergent surface superconductivity in the topological insulator Sb2Te3.
Direct evidence from transport, the unprecedentedly large diamagnetic screening, and the presence of ∼25 meV gaps detected by scanning tunnelling spectroscopy reveal the superconducting condensate to emerge first in surface puddles, with the onset of global phase coherence at ∼9 K.
Electron–hole asymmetry of the topological surface states in strained HgTe
This work establishes the existence of exclusively surface-dominated transport via the observation of an ambipolar surface quantum Hall effect and quantum oscillations in the Seebeck and Nernst effect, and shows that, whereas the thermopower is diffusion driven for surface electrons, both diffusion and phonon drag contributions are essential for the hole surface carriers.

Topological insulators are materials that have a bulk band gap similar to commonly known insulators, but have conducting states on their edge or surface. The bulk band gap is generated because of the

A topological Dirac insulator in a quantum spin Hall phase
The direct observation of massive Dirac particles in the bulk of Bi0.9Sb0.1 is reported, which suggests that the observed surface state on the boundary of the bulk insulator is a realization of the ‘topological metal’, which has potential application in developing next-generation quantum computing devices that may incorporate ‘light-like’ bulk carriers and spin-textured surface currents.
