Abstract: Abstract Iridium doped Bi2Se3 crystals have been prepared by self-flux method. Their crystalline, morphological, Raman spectra, and transport properties were investigated. The obtained crystals have typical topological insulator characteristics. Same layered structure was confirmed for… read more here.

Abstract: Time-reversal symmetry is broken by magnetic doping in topological insulators (TIs). An energy gap at the Dirac point opens and thus, generates numerous surface carriers. TI nanostructures are an ideal platform to investigate exotic surface… read more here.
