Kondolike zerobias conductance anomaly in a threedimensional topological insulator nanowire
Zerobias anomalies in topological nanowires have recently captured significant attention, as they are possible signatures of Majorana modes. Yet there are many other possible origins of zerobias peaks in nanowires—for example, weak localization, Andreev bound states, or the Kondo effect. Here, we discuss observations of differentialconductance peaks at zerobias voltage in nonsuperconducting electronic transport through a 3D topological insulator (Bi _{1.33}Sb _{0.67})Se _{3} nanowire. The zerobias conductance peaks show logarithmic temperature dependence and often linear splitting with magnetic fields, both of which are signatures of the Kondo effect in quantum dots. As a result, we characterize the zerobias peaks and discuss their origin.
