Polarization Processes in Thin Layers of Amorphous MoS₂ Obtained by RF Magnetron Sputtering

Abstract: The polarization processes in thin layers of amorphous molybdenum disulfide MoS₂ are studied by dielectric spectroscopy techniques. The process of dipole-relaxation polarization is observed. The microscopic parameters of the system are calculated, and the relaxation time of the dipole-polarization process, as well as the activation energies E_a and E_σ of the relaxation process and conductivity, respectively, are determined. The fact that the two activation energies are close to each other suggests that the processes of relaxation and charge transport are driven by the same mechanism.
