论文摘要
二维（2D）超导体的最新发现发现了包括涡旋物质在内的物理特性的各个新方面。在本文中，我们报告了离子门控MOS2中零磁场的传输属性和动力学相图。除了在电流 - 电压特性中的普遍跳跃外，还显示了Berezinskii-Kosterlitz-thowless（BKT）过渡的明确证据，我们观察到电阻的温度和电流衍生物中的多个峰，基于在电流平面中的动态相图的构建。我们发现了涡流抗体对的电流诱导的动力状态，其中包含相位滑道线。此外，我们介绍了门控MOS2中涡旋的全球相图，该图捕获了清洁2D超导体的涡旋物质。
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.
