Thin Film Metallic Glasses (TFMGs) are an emerging class of materials, with the potential to realize exceptional combinations of mechanical and electrical properties so far unachievable by conventional crystalline alloys. Specifically, TFMGs are characterized by the lack of long-range atomic periodicity together with the absence of defects common to crystalline materials, resulting in outstanding mechanical properties and metallic electrical conductivity and making them interesting candidates within the growing domain of stretchable electronics. Despite these potential applications, the synthesis of advanced TFMGs with engineered microstructure and the understanding of their mechanical/electrical properties is barely tackled, requiring the development of novel strategies for their synthesis and cutting-edge techniques for sub-micrometer scale characterization.In this context, the EGLASS project aims to develop advanced TFMGs with tailored nanoscale design such as interfaces with large free-volume, cluster-assembled structures, multilayers and amorphous films with embedded nanocrystals resulting in outstanding combination of mechanical/electrical properties. Cutting-edge in situ characterization techniques including compression of micropillars and measurement of local electrical properties combined with advanced structural characterization (HRTEM/APT) will be employed to grasp the fundamental physical behaviour and understand the connection between the structure and mechanical/electrical properties. The project will merge the unique expertise of LSPM (sputtering, pulsed laser deposition and in situ mechanical characterization, Ab initio molecular dynamics simulations) and KIT (advanced synthesis routes, structural/electrical characterization) fostering the application of TFMGs as future materials for stretchable electronics.The joint French-German team merges the recognized expertise in different fields of materials science and their deep knowledge of metallic glasses and thin films. In a close cooperation, the teams will investigate the following fundamental issues of TFMGs: (i) synthesis of novel TFMGs architectures, (ii) microscale mechanical/electrical properties, (iii) relation composition-microstructure-mechanical/electrical properties focusing on key parameters to increase mechanical properties and electrical conductivity, (iv) use of TFMGs for stretchable electronics combining together adhesion, stretchability, conductivity.

薄膜金属眼镜（TFMG）是一类新兴的材料，有可能实现传统晶体合金无法实现的机械和电性能的非凡组合。具体而言，TFMG的特征是缺乏远距离原子周期性，以及没有结晶材料常见的缺陷，从而产生了出色的机械性能和金属电导率，并使它们在可伸缩电子产品的不断增长的领域中变得有趣。尽管有这些潜在的应用，但几乎没有解决与工程微观结构的高级TFMG及其机械/电气特性的理解，这需要开发其合成的新型策略和尖端微米计尺度表征。聚集组装的结构，多层膜和具有嵌入式纳米晶体的无定形膜，从而导致机械/电气性能的出色组合。最先进的原位表征技术，包括压缩微柱和对局部电气的测量以及先进的结构表征（HRTEM/APT）的测量，以掌握基本的物理行为并了解结构与机械/电气性能之间的联系。该项目将融合LSPM（溅射，脉冲激光沉积和原位机械表征，从头启动的分子动力学模拟）和KIT（高级合成途径，结构/电气表征）促进TFMG作为可伸展电子的未来材料的材料，并在其上具有材料的范围，并在其上的材料进行了培训。薄膜。在密切合作中，团队将研究TFMG的以下基本问题：（i）新型TFMGS架构的合成，（ii）显微镜机械/电气特性，（iii）关系组成 - 形成 - 微体结构机械/机械/电气/电气/电气的集中于关键参数，以增加机械性能的范围（TF）（TF）（TF）（TF）（TF）（TF）（IV）（IIV），粘附，可伸缩性，电导率。
