Signature of pseudo-diffusive transport in mesoscopic topological insulators

Saurav Islam, Semonti Bhattacharyya, Hariharan Nhalil +2

One of the unique features of Dirac Fermions is pseudo-diffusive transport by evanescent modes at low Fermi energies when the disorder is low. At higher Fermi energies i.e. carrier…

Universal conductance fluctuations and direct observation of crossover of symmetry classes in topological insulators

Saurav Islam, Semonti Bhattacharyya, Hariharan Nhalil +2

A key feature of topological insulators (TI) is symplectic symmetry of the Hamiltonian which changes to unitary when time reversal symmetry is lifted and the topological phase tran…
