Realization of a vertical topological p–n junction in epitaxial Sb2Te3/Bi2Te3 heterostructures
Three-dimensional (3D) topological insulators are a new state of quantum matter, which exhibits both a bulk band structure with an insulating energy gap as well as metallic spin-polarized Dirac fermion states when interfaced with a topologically trivial material. There have been various attempts to...
