利用固体电解质来调节薄膜材料中的载流子密度是一种新兴的技术，在基础研究和应用研究中都有潜在的应用。到目前为止，只有含有质子和锂离子等小离子的材料才被用来演示选通效应。在这里，我们报告了一种实验室合成的钠离子基固体电解质的研究，它显示出比以前报道的锂离子基固体电解质更强的调节石墨烯中载流子密度的能力。我们的发现可能会刺激人们寻找更适合于门控应用的固体电解液，利用许多为电池研究开发的现有材料。
Using a solid electrolyte to tune the carrier density in thin-film materials is an emerging technique that has potential applications in both basic and applied research. Until now, only materials containing small ions, such as protons and lithium ions, have been used to demonstrate the gating effect. Here, we report the study of a lab-synthesised sodium-ion-based solid electrolyte, which shows a much stronger capability to tune the carrier density in graphene than previously reported lithium-ion-based solid electrolyte. Our findings may stimulate the search for solid electrolytes better suited for gating applications, taking benefit of many existing materials developed for battery research.
