The theory of electron transport processes taking place in mesoscopic systems, which we have examined, can be investigated with the so-called rate equation formalism. This allows us to theoretically test the quantum dots’ transport processes which are defined on a few-layer transition-metal dichalcogenide (e.g. MoS2 ) systems. In such systems, quantum dots’ energy levels have three-fold degeneracy, the behaviour of electrons can be described by a three-fold symmetry which is rare in solid-state physics, resulting an interesting and novel behaviour in the transport processes. We have analytically examined the transport processes of single quantum dots controlled by the so-called Coulomb blockade with the help of rate equations, while the degeneracy of the energy level is 3- or m-fold. We have determined the dependency of system-specific quantities (transport current, current noise and conductivity) on the external parameters. As a next step, we examined the transport properties of double quantum dots in the case when the degeneracy of the energy levels is m-fold. In addition to determining the optimal charge configuration, we also analyzed the effects in the transport current due to the so-called Pauli blockade.
