Abstract
The topological insulator is characterized by insulating bulk and conducting surface states, which is a kind of new solid material. Different from traditional solid materials, topological insulator is protected by time-reversal symmetry. The special structure of topological insulator gives it special properties, such as non-dissipative electrical transmission and high carrier mobility, which make it potential for a wide range of applications in a large number of fields. This paper describes the development of topological insulator starting from von klitzing's discovery of the quantum Hall effect [1], followed by a brief description of several methods of synthesizing the topological insulator and characterization of its properties, finally introduces its applications in three fields: photodetectors, spinctronic devices, and field effect transistors.
