Weak localization effect in topological insulator micro flakes grown on insulating ferrimagnet BaFe12O19
Abstract Many exotic physics anticipated in topological insulators require a gap to be opened for their topological surface states by breaking time reversal symmetry. The gap opening has been achieved by doping magnetic impurities, which however inevitably create extra carriers and disorder that undermine the electronic transport. In contrast, the …
