- W2808274953 abstract "We examined whether samarium hexaboride (SmB₆) is a topological insulator, or notby reviewing and reanalyzing all published experimental results to date. Despite thefact that the SmB₆ has long been known as a Kondo insulator, with strong correlationsand band hybridization, it is still of great interest because of low-temperaturetransport anomalies which have recently been interpreted as evidence that SmB₆ is atopological insulator. SmB₆ behaves electronically at high temperature like an insulator,and at low temperature its resistance mysteriously saturates.We studied de Haas van-Alphen quantum oscillation results to resolve the Fermisurface topology in this material. Although dHvA measurement may be consistentwith two-dimensional conducting electronic states, we find an elongated 3D ellipsoidalFermi surface is also consistent with the experimental results. Furthermore, resistancemeasurements also can give some evidence of SmB₆ surface conductivity, by studyingdifferent geometries to determine whether the conduction is dominated by the surfaceor the bulk. Also, we simulated the conductivity of a thin sample to assess whether theexperimental measurements on their sample are consistent with surface conductivity.After analyzing these experiments and others, our conclusion is that the mainexperimental results can be described as either bulk or surface conduction, but resistivitymeasurements strongly suggest surface conduction. Even if further studiesprove the surface conductivity, further studies will be required to show that SmB₆ is a topological material." @default.
