Although the topological insulating phenomenon was observed at up to 100 kelvins, the superconducting behavior in the new work occurred at a much lower temperature of about 1K. This material has the advantage of entering the superconducting state with one of the lowest densities of electrons for any 2 … 2019-06-01 Ruck’s bismuth-rhodium-iodine material stays a topological insulator at temperatures up to roughly 2,000 K (Nat. Mater. 2013, DOI: 10.1038/nmat3570).

This review presents a pedagogical account on topological insulator materials with an emphasis on basic theory and materials properties. Topological insulators Topological insulators are insulating materials that conduct electricity on their surface via special surface electronic states The surface states of topological insulators are topologically protected, which means that unlike ordinary surface states they cannot be destroyed by impurities or imperfections Topological insulators represent a new quantum state of matter which is characterized by peculiar edge or surface states that show up due to a topological character of the bulk wave functions. This review presents a pedagogical account on topological insulator materials with an emphasis on basic theory and materials properties. Topological insulators (TIs) are new states of quantum matter with a full insulating gap in the bulk of the material and gapless Dirac fermion states on the surface (1–3).
