A newly emerging field of application has described the use of low molecular weight ionic liquids as a dielectric gating interface within functional FET devices. In such devices, a thin layer of an ionic liquid is placed on top of the gate: this often very thin layer (usually in the range of ~ tens of nanometers (nm)) of an ionic liquid significantly alters the gating properties of an FET, leading to substantially improved switching of the gate, thus considerably accelerating the charge transport properties within the FET (due to the formation of an electric double layer (ELD)). The overall goal of this project is the generation of polymeric ionic liquids (POILs) and ion gels with embedded nanoscopic domains to address the design of conductive nanoconfined "IL-droplets" for use as gated dielectrics in FETs. Understanding of the complex interplay between the structure and properties (e.g. overall conductivity) and the morphology of ionic liquid- based materials will be obtained. Further, an intensive study of the interaction mechanism stability and reversibility of the processes involved in ionic liquid- gating processes on inorganic substrates should enable the profound evaluation on applicability of these polymeric materials for gating in FETs. The aim is to select an appropriate ionic liquid- based polymeric material capable to generate a nanoscopic pattern in the underlying metal-oxide.

一个新兴的应用领域已经描述了低分子量离子液体作为功能FET器件内的介电门控界面的用途。在这样的器件中，离子液体的薄层被放置在栅极的顶部：这层通常很薄离子液体的浓度（通常在~几十纳米（nm）的范围内）显著改变FET的选通性质，导致栅极的切换显著改善，因此显著加速FET内的电荷传输性质（由于双电层（ELD）的形成）。该项目的总体目标是生成具有嵌入式纳米结构域的聚合物离子液体（POIL）和离子凝胶，以解决用作FET中的门控微滴的导电纳米限制的“IL-液滴”的设计。将获得对基于离子液体的材料的结构和性质（例如总体电导率）以及形态之间的复杂相互作用的理解。此外，深入研究离子液体在无机基底上的门控过程中所涉及的过程的相互作用机制、稳定性和可逆性，应该能够对这些聚合物材料用于FET门控的适用性进行深刻的评价。目的是选择能够在下面的金属氧化物中产生纳米级图案的适当的基于离子液体的聚合物材料。
