Electrically tunable quantum spin Hall state in topological crystalline insulator thin films
Based on electronic structure calculations and theoretical analysis, we predict the (111) thin films of the SnTe class of three-dimensional (3D) topological crystalline insulators (TCIs) realize the quantum spin Hall phase in a wide range of thicknesses. The nontrivial topology originates from the intersurface coupling of the topological surface states of TCIs in the 3D limit. The intersurface ...
متن کاملSpin-filtered edge states with an electrically tunable gap in a two-dimensional topological crystalline insulator.
Three-dimensional topological crystalline insulators were recently predicted and observed in the SnTe class of IV-VI semiconductors, which host metallic surface states protected by crystal symmetries. In this work, we study thin films of these materials and expose their potential for device applications. We demonstrate that thin films of SnTe and Pb(1-x)Sn(x)Se(Te) grown along the (001) directi...
متن کاملUnexpected Au Alloying in Tailoring In-Doped SnTe Nanostructures with Gold Nanoparticles
Materials with strong spin-orbit interaction and superconductivity are candidates for topological superconductors that may host Majorana fermions (MFs) at the edges/surfaces/vortex cores. Bulk-superconducting carrier-doped topological crystalline insulator, indium-doped tin telluride (In-SnTe) is one of the promising materials. Robust superconductivity of In-SnTe nanostructures has been demonst...
متن کاملTopological surface transport properties of single-crystalline SnTe nanowire.
SnTe has attracted worldwide interest since its theoretical predication as topological crystalline insulator. Because of promising applications of one-dimensional topological insulator in nanoscale electronics and spintronics device, it is very important to realize the observation of topological surface states in one-dimensional SnTe. In this work, for the first time we successfully synthesized...
متن کاملStrain engineering Dirac surface states in heteroepitaxial topological crystalline insulator thin films.
The unique crystalline protection of the surface states in topological crystalline insulators has led to a series of predictions of strain-generated phenomena, from the appearance of pseudo-magnetic fields and helical flat bands to the tunability of Dirac surface states by strain that may be used to construct 'straintronic' nanoswitches. However, the practical realization of this exotic phenome...
