通过扩展可达态密度使存储电荷增加四倍
Quadrupling the stored charge by extending the accessible density of states
摘要：
纳米储能、能量收集和功能器件是集成自供电系统的三个关键组成部分。在这里，我们报告的纳米电化学器件与近三倍增强存储电荷的场效应下。我们证明了场效应晶体管不仅可以作为纳米器件中的功能组件，而且还可以作为纳米储能块的放大器。这种不寻常的能量储存增加归因于具有宽范围的可访问电子态密度（EDOS），因此氧化还原反应发生在纳米线内，而不限于表面。MoS2的初步结果表明，这种场效应调制的储能机制也可以应用于许多其他氧化还原活性材料。我们的工作展示了场效应在储能器件中的新应用，作为一种通用策略，可以改善离子扩散和活性材料的表面活性离子浓度，这可以大大提高纳米器件的电荷存储能力。场效应储能器件的制造工艺也与微技术兼容，可以集成到其他微器件和纳米器件中。
英文摘要：
Nanosized energy storage, energy-harvesting, and functional devices are the three key components for integrated self-power systems. Here, we report on nanoscale electrochemical devices with a nearly three-fold enhanced stored charge under the field effect. We demonstrated the field-effect transistor can not only work as a functional component in nanodevices but also serve as an amplifier for the nanosized energy storage blocks. This unusual increase in energy storage is attributed to having a wide range of accessible electronic density of states (EDOS), hence redox reactions are occurring within the nanowire and not being confined to the surface. Initial results with MoS2 suggest that this field effect modulated energy storage mechanism may also apply to many other redox-active materials. Our work demonstrates the novel application of the field-effect in energy storage devices as a universal strategy to improve ion diffusion and the surface-active ion concentration of the active material, which can greatly enhance the charge storage ability of nanoscale devices. The fabrication process of the field-effect energy storage device is also compatible with microtechnology and can be integrated into other microdevices and nanodevices.
