Combined Assembly by Soft and Hard chemistry, from hierarchically ordered nanoparticle/block-copolymer composites to non-volatile memory devices (CASH-Memory)

在这个项目中(软化学和硬化学现金存储器的组合组装)，我们将研究不同掺杂水平和相(柱状、片状和倒柱状)的NP掺杂嵌段共聚物PS-b-PEO作为功能性非挥发性存储层。我们的目标是两个不同的存储概念：i)用于有机TFT的浮栅方法；ii)作为阵列兼容概念的导电桥单元(CB-RAM)。除了与设备相关的主题外，我们还将调查我们系统的一般科学问题(PS-b-PEO/NPs)，以理解和实现这些复杂的记忆概念。这些问题涉及SAM表面处理的相取向，具有亲水性或疏水性或两者兼有的核壳纳米粒子的选择性负载，与NP浓度和NP尺寸有关的相形态，以及使用同壳或Janus型纳米粒子在相中或在相界面处优先积累NPs。通过我们的项目，我们希望为现金系统提供科学的见解，并为可靠、持久和长期稳定的运行提供合适的非易失性存储平台，并有可能在灵活的电子应用中实现。

Within this project (Combined Assembly by Soft and Hard chemistry CASH Memory) we will investigate NP-doped block-copolymer PS-b-PEO in their various doping levels and phases (cylindric, lamellar and inverted cylindric) as functional non-volatile memory layers. We target two different memory concepts i) floating gate approach for organic TFTs and ii) conductive bridging cells (CB-RAM) as array-compatible concept. Besides the device related topics, we will investigate general scientific questions of our system (PS-b-PEO/NPs) in order to understand and to realize those complex memory concepts. Those questions relate to phase orientation by SAM surface treatment, to selective load of phases with hydrophilic or hydrophobic or both kinds of our core-shell NPs, to the phase morphology as function of NP concentration and NP size and the preferential accumulation of NPs in phase or at the phase interface by using homo-shells or Janus-type NPs. From our project we expect to provide both, scientific insight into CASH systems and suitable non-volatile memory platforms for reliable, endurable and long term stable operation with potential to become implemented in flexible electronics applications.
