Tailored heterepitaxy of nanostructured thin films for de novo organic electronic devices under stress

该项目的目标是生产纳米结构，其中功能有机材料以受控的方式组织，从而调整电荷转移和传输。异质外延有机材料受到越来越多的关注，在惰性衬底上控制两种不同材料的单层沉积将为研究两者之间界面上的电荷转移提供机会。此外，该项目将独特地致力于研究基底弯曲对有机薄膜结构的影响。柔性衬底的使用被广泛认为是未来电子器件发展的前景，但机械应力对有机器件功能层中分子组织的影响尚不清楚。这项研究的结果将为有机材料之间的界面以及它们在使用一系列表征方法进行机械变形时所经历的结构变化提供独特的见解。

The objective of the project is to produce nanostructures where functional organic materials are organised in a controlled manner such that the charge transfer and transport are tailored. Heteroepitaxial organic materials are of increasing interest, and the controlled deposition of two monolayers of different materials on an inert substrate will afford the opportunity to study charge transfer at the interface between the two. In addition, the project will uniquely aim to study the effect of bending of the substrate on the structure of the organic films. The use of flexible substrates is widely implied as promising for the development of future electronic devices, but the consequences of mechanical stress on molecular organisation in the functional layers of organic devices is unknown. The results of the research will provide unique insight into interfaces between organic materials and the changes in structure they undergo upon mechanical deformation using a battery of characterisation methods.
