Enhanced transport length of spin-helical Dirac fermions in disordered 3D topological insulators

J. Dufouleur, L. Veyrat, B. Dassonneville +7

The transport length $l_{\text{tr}}$ and the mean free path $l_{\text{e}}$ are experimentally determined for bulk and surface states in a Bi${}_2$Se${}_3$ nanoribbon by quantum transpo…
