Transition frequency and dynamic of polaron in transition metal dichalcogenide under radiowave and microwave

Abstract

We investigated the transition frequency and dynamic of polaron in transition metal dichalcogenide (TMD) under the radiowave and the microwave using Pekar variational method. We calculated the ground and first excited states energies of polaron, the magnitude of the bandgap modulation, the mobility and the lifetime of polaron are derived. Due to the polaron’s superposition states in TMD, the qubit is formed, and the transition frequency is derived in order to value the information transfer. Our results demonstrated that: on one hand, the frequency of the microwave and the radiowave create fluctuation in the states energy of the polaron and the magnitude of the bandgap modulation. On the other hand, we found that their amplitudes increase the states energies, the lifetime and the mobility of the polaron but reduces the magnitude of the bandgap modulation. We also found that the radiowave and the microwave allow the information transfer and are helpful for controlling the state of a system.
