Plasma synthesis of innovative thin films and nanomaterials for device fabrication

******材料科学与工程的创新在于我们能够在纳米尺度上控制材料的结构，从而设计出具有出色功能特性（电学、光学、磁性、光催化等）的新材料。在纳米尺度上排列物质的最有力手段之一是使用等离子体，因为等离子体具有非凡的能力，可以同时提供各种粒子，即离子、中性原子和自由基、光子以及非平衡环境。因此，等离子体在以薄膜或纳米材料的形式合成无机和有机材料方面是独一无二的。我的全球愿景是继续从事这个非常肥沃的研究领域，在各个学科（物理，化学和工程）的前沿，在材料科学和技术方面产生令人兴奋的新知识，并设想创新的材料工艺，可以用于下一代日益复杂，性能和功能的射频和光子器件，或用于先进的环境应用，如水处理。******在此背景下，我的研究计划包括三个项目，涉及等离子体和材料科学的基本问题。由于有了探测物质动力学的新工具，第一个项目旨在加深对由激光产生的等离子体合成的掺杂二氧化钒中控制金属-绝缘体转变的物理现象的理解。第二个项目旨在研究用于先进射频器件的人工多铁材料的增长，利用我们在先进纳米制造技术方面的专业知识，特别是基于等离子体的材料合成和蚀刻。第三个项目旨在了解低温大气压等离子体对纳米结构纤维素功能化的严格控制。******除了这些项目是我长期愿景的核心，我的研究计划还包括短期和中期项目，以响应各个领域的特定经济和环境需求，包括能源，光子学和光催化。短期项目包括，例如，与MPB通信公司合作开发用于微型和纳米卫星的基于二氧化钒的智能辐射装置，与AEPONYX合作开发用于制造集成光子器件的最先进纳米制造工艺，以及与Magnus合作研究用于水处理的纳米结构可见光驱动异质结光催化剂。最后，这项研究的一个主要好处是培训了高素质的人才，这些人才将构成未来学术界和工业界的专业知识库。

******Innovation in materials science and engineering resides in our ability to control the structure of materials at the nanoscale in order to design new materials with outstanding functional properties (electrical, optical, magnetic, photocatalytic, etc.). One of the most powerful means to arrange matter at the nanoscale is to use plasmas due to their exceptional ability to provide simultaneously a variety of particles, namely ions, neutral atoms and radicals, and photons, together with a non-equilibrium environment. Plasmas are therefore unique to synthesize inorganic and organic materials in the form of either thin films or nanomaterials. My global vision is to continue to engage myself in this very fertile research field at the cutting edge of various disciplines (physics, chemistry and engineering) to generate exciting new knowledge in materials science and technology, and to conceive innovative materials processes that can be exploited for the next generation of RF and photonic devices of ever-increasing complexity, performance and functionality or for advanced environmental applications such as water treatment. ******In this context, my research program includes three projects tackling fundamental issues in plasma and materials science. Thanks to the newly available tools to probe matter dynamics, the first project aims to deepen the understanding of the physical phenomena governing the metal-insulator transition in doped vanadium dioxide synthesized by laser-produced plasmas. The second project intends to investigate the growth of artificially built multiferroic materials for advanced RF devices, capitalizing on our expertise in advanced nanofabrication techniques, in particular plasma-based materials synthesis and etching. The third project aims to understand low-temperature atmospheric pressure plasmas for tightly controlling nanostructured cellulose functionalization. ******Besides these projects that are at the heart of my long-term vision, my research program also encompasses short- and medium-term projects that respond to specific economic and environmental needs in various sectors including energy, photonics, and photocatalysis. Short-term projects include, for example, the development of vanadium dioxide-based smart radiator devices for micro- and nanosatellites in collaboration with MPB Communications, the elaboration of state-of-the-art nanofabrication processes for manufacturing integrated photonic devices with AEPONYX and the investigation of nanostructured visible light-driven heterojunctions photocatalysts for water treatment with Magnus. Finally, a major benefit stemming from this research is the training of highly qualified personnel that will constitute a future pool of expertise for both academia and industry.
