  Recent discoveries of two-dimensional (2D) superconductors have uncovered
various new aspects of physical properties including vortex matter. In this
paper, we report transport properties and a dynamical phase diagram at zero
magnetic field in ion-gated MoS2. In addition to the universal jump in the
current-voltage characteristic showing unambiguous evidence of the
Berezinskii-Kosterlitz-Thouless (BKT) transition, we observed multiple peaks in
the temperature- and current-derivative of the electrical resistance, based on
which a dynamical phase diagram in the current-temperature plane was
constructed. We found current-induced dynamical states of vortex-antivortex
pairs, containing that with the phase slip line. Also, we present a global
phase diagram of vortices in gated MoS2 which captures the nature of vortex
matter of clean 2D superconductors.
