The theoretical development and prospect of two-dimensional topological insulators
Abstract
Topological insulators can be described as rediscovery of band theory, where numerous secrets on edges and surfaces are unearthed. During the process of rediscovery, the concept of topology into novel theoretical models of topological insulators played a crucial role. This paper aims to give an introduction to the theoretical development of two-dimensional topological insulators in a nutshell, so it is indispensable and efficient to relate topological invariant with the band structure of topological insulators and use specific and vital theoretical models to reveal novel phenomena in those materials. The main focus of the paper is placed on historic landmarks in the theoretical development of two-dimensional topological insulators where fundamental concepts and models have paved the way for further enrichment of family of topological materials and experimental realizations.
