  We investigate the propagation of electrons in a circular quantum dot of
monolayer Molybdenium disulfide MoS_2, subjected to an electric potential.
Using the continuum model, we present analytical expressions for the
eigenstates, scattering coefficients, scattering efficiency, and radial
component of the reflected current and electron density. We identify two
scattering regimes as a function of physical parameters such as incident
electronic energy, potential barrier, and quantum dot radius. For the incident
electron low energy, we show that there is an appearance of scattering
resonances. Also, we note that the Far-field scattered current has distinct
preferred scattering directions.
