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（软硬化学CASH Memory组合组装）中，我们将研究np掺杂嵌段共聚物PS-b-PEO在不同掺杂水平和相（圆柱形、层状和倒圆柱形）下的功能非易失性存储层。我们针对两种不同的存储概念i)有机tft的浮动门方法和ii)导电桥接细胞（CB-RAM）作为阵列兼容的概念。除了器件相关的主题，我们将研究我们的系统（PS-b-PEO/NPs）的一般科学问题，以理解和实现这些复杂的内存概念。这些问题涉及到SAM表面处理的相取向，亲水或疏水或两种核壳NPs的选择性相负载，作为NP浓度和NP大小的相形态函数，以及使用同壳或janus型NPs在相或相界面上优先积累NPs。从我们的项目中，我们希望提供对CASH系统和合适的非易失性存储平台的科学见解，以实现可靠，耐用和长期稳定的运行，并有可能在柔性电子应用中实现。

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.
