Transport Experiments on Three-Dimensional Topological Insulators

摘要: Abstract The discovery of topological insulators as a new state matter has generated immense interest in this class materials. Three-dimensional (3D) are characterized by the presence an odd number families Dirac fermions—ideally one- at each their surfaces. Angle-resolved photoemission experiments have demonstrated expected fermions, but it is clear that to explore electronic properties these systems, transport measurements many different device geometries called for, just been case for fermions graphene. In chapter we review status studies through 3D early summer 2012, after first generation performed. results provide indications surface well evidence nature. However, no textbook “manifestation” reported so far Indeed, also show investigations severely hampered material quality most cases, because effect high conductivity bulk, low carrier mobility, technical difficulties hampering fabrication, and other reasons. chapter, attempt give balanced overview work done during period obtained, stressing implications limits observations literature.
