The study of the exotic bound states in atomically thin semiconductors with a transition metal atom has attracted a great deal of interest in quantum field theory. The reality of transition metal dichalcogenide monolayer materials has been the subject of intense concern among theoreticians and experimenters in recent years. To obtain transition metal dichalcogenide monolayer materials with specific properties; it is extremely important to develop particular strategies to obtain specific exotic structures. These exotic structures are considered to be in a two-particle/quasiparticle bound state: exciton and biexciton (exciton-exciton), exciton-polariton, polariton-phonon. Quantum field theory, in its widest sense, is a method to control and achieve reasonable goals. Control of such states enables the control of properties and access to a range of quantum properties, otherwise inaccessible. The relativistic mass spectrum and relativistic constituent mass of particles in monolayer transition metal dichalcogenide monolayer materials have been calculated using the relativistic Schrödinger equation with strong Coulomb-type potential between the electron and hole. The ground state of the transition metal dichalcogenide monolayer has been studied. Therefore, the investigation may indicate promising applications in quantum information processing and electronic device technologies based on the semiconductor quantum dots system. پرونده مقاله
