Topological Insulator Materials

Understand

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.
• After presenting a historical perspective and basic theories of topological insulators, it discusses all the topological insulator materials discovered as of May 2013, with some illustrative descriptions of the developments in materials discoveries in which the author was involved.
• A summary is given for possible ways to confirm the topological nature in a candidate material.
