Abstract
The basic concepts of excitons and exciton complexes in TMD materials are discussed in this work, including bright and dark excitons, neutral and charged excitons, intralayer and interlayer excitons, and others. Further, methods are reviewed, of manipulating and tuning exciton complexes in TMD materials through strain, electrical and magnetic field, interlayer twist between neighboring layers. Finally, future research directions and applications of excitonic device are discussed.
