Tunable Interaction-Induced Localization of Surface Electrons in Antidot Nanostructured Bi<sub>2</sub>Te<sub>3</sub> Thin Films
Recently, a logarithmic decrease of conductivity has been observed in topological insulators at low temperatures, implying a tendency of localization of surface electrons. Here, we report quantum transport experiments on the topological insulator Bi2Te3 thin films with arrayed antidot nanostructures. With increasing density of the antidots, a systematic decrease is …
