Prominent metallic surface conduction and the singular magnetic response of topological Dirac fermion in three-dimensional topological insulator Bi(1.5)Sb(0.5)Te(1.7)Se(1.3)
We report semiconductor to metal-like crossover in the temperature dependence of resistivity (ρ) due to the switching of charge transport from bulk to surface channel in three-dimensional topological insulator Bi(1.5)Sb(0.5)Te(1.7)Se(1.3). Unlike earlier studies, a much sharper drop in ρ(T) is obser...
