  We study the Dirac electron scattering problem on a potential barrier in a
circular quantum dot of Monolayer Molybdenum Disulfide quantum dot MoS2
subjected to magnetic flux. By solving Dirac's equation, we formulate
analytical expressions for the eigenstates, scattering coefficients, scattering
efficiency, and the reflected current's radial component. We show that the
scattering coefficients, the scattering efficiency, and the radial component of
the reflected current depend explicitly on the magnetic flux. The magnetic flux
may cause a slight shift in the oscillation position of the scattering
coefficients. For scattering efficiency, magnetic flux may also lead to a
slight shift in their oscillation position and an increase in amplitude when
the magnetic flux decreases.
