The goal of Project C1 is to analyze the effect of the three-dimensional confinement on the switching properties of individual resistively switching nanoparticles. As model compound for resistively switching metal oxides we will develop new synthetic routes to obtain HfO2 with variable structure and composition. As nanoparticulate phase change materials we will vary the composition of Sb-based materials to ap-proach the conventional bonding regimes of metallic, covalent and ionic bonding and analyze the inter-play of size and material composition on the crystallization features of the respective materials. Individual NPs will be integrated in lithographically fabricated nanogap devices (fabricated in Z4) as an approach for integrating chemically designed building blocks into nanoelectronic circuitry.

项目1的目标是分析三维限制对单个电阻开关纳米颗粒开关特性的影响。作为电阻开关金属氧化物的模型化合物，我们将开发新的合成路线，以获得结构和组成可变的HfO2。作为纳米颗粒相变材料，我们将改变Sb基材料的组成，以探讨传统的金属键、共价键和离子键的键合方式，并分析尺寸和材料组成对各自材料结晶特性的影响。单个NPs将被集成到光刻制造的NanoGap器件中(在Z4制造)，作为一种将化学设计的积木集成到纳米电子电路中的方法。
