Signatures of long-range-correlated disorder in the magnetotransport of ultrathin topological insulators
D. Nandi, B. Skinner, G. H. Lee +10
In an ultrathin topological insulator (TI) film, a hybridization gap opens in the TI surface states, and the system is expected to become either a trivial insulator or a quantum sp…

Logarithmic singularities and quantum oscillations in magnetically doped topological insulators
Debaleena Nandi, Inti Sodemann, Kevin Shain +9
We report magnetotransport measurements on magnetically doped (Bi,Sb)Te films grown by molecular beam epitaxy. In Hallbar devices, logarithmic dependence on temperature and…
