Crossover between Weak Antilocalization and Weak Localization in a Magnetically Doped Topological Insulator
Crossover between Weak Antilocalization and Weak Localization in a Magnetically Doped Topological Insulator
Topological insulators (TI) are a new class of quantum materials with insulating bulk enclosed by topologically protected metallic boundaries. The surface states of three-dimensional TIs have spin helical Dirac structure, and are robust against time reversal invariant perturbations. This extraordinary property is notably exemplified by the absence of backscattering by …
