The superconducting transition manifests itself as an emergence of the zero resistance state below 2.8 K. $I-V$ characteristics exhibit sharp and hysteretic switching between superconducting and normal states with well-defined critical and retrapping currents. The two-dimensional (2D) critical current density $J_\\mathrm{2D,c}$ is estimated to be as high as $1.8 \\ \\mathrm{A/m}$ at 1.8 K.
