标题： Observation of surface superconductivity in bulk polycrystalline MoS2 induced by electric double-layer doping

摘要： 我们报告了在体多晶MoS2表面通过电双层掺杂观察到电场诱导的超导性。 在离子液体环境中施加的栅极电压系统地增加了载流子密度，导致低温下的绝缘体-金属转变和电阻急剧下降，表明存在超导性。 超导性的起始温度强烈依赖于从电导率推断出的载流子密度，显示出显著增加并最终饱和。 与之前局限于单晶MoS2的研究不同，我们的结果表明超导性也可以在多晶系统中通过静电方式诱导，拓宽了在更广泛材料中探索门控超导性的范围。 显示英文摘要

摘要： We report the observation of electric-field-induced superconductivity on the surface of bulk polycrystalline MoS2 using electric double-layer doping. A gate voltage applied in an ionic liquid environment systematically increased carrier density, leading to an insulator-to-metal transition and a sharp resistance drop at low temperatures, indicating superconductivity. The onset temperature of superconductivity strongly depended on carrier density inferred from conductance, showing a significant increase and eventual saturation. Unlike prior studies limited to single-crystalline MoS2, our results demonstrate that superconductivity can also be electrostatically induced in polycrystalline systems, broadening the scope for exploring gate-controlled superconductivity in a wider range of materials.
