We investigate the propagation of electrons in a circular quantum dot monolayer Molybdenium disulfide MoS_2, subjected to an electric potential. Using continuum model, we present analytical expressions for eigenstates, scattering coefficients, efficiency, and radial component reflected current electron density. identify two regimes as function physical parameters such incident electronic energy...

The oxirene is an unsaturated heterocyclic molecule with one oxygen atom and two carbon atoms. Its hydrogenation has been performed on two catalytic site based on molybdenum disulfide (MoS2) and tungsten disulfide (WS2) of MoS3H3 and WS3H3 type, respectively. The calculations were carried out using the SCF and MP2 methods and B3LYP functional calculations. The results obtained showed that the h...

A simple band model such as the effective mass approximation (EMA) can be used to quickly obtain lower-energy region for structure of monolayer molybdenum disulfide. But EMA cannot give correct description in higher-energy region. To address this major issue, we propose an analytical calculation (ABC) study Important parameters ABC are obtained by fitting three-direction disulfide from first-pr...
