项目摘要
This research focuses on multiferroic materials exhibiting simultaneously magnetic and ferroelectric properties. Though a field of intense research, there are still very few known multiferroic materials at room temperature, and these materials still need a deeper understanding of their properties, in particular the coupling between the ferroelectric and magnetic properties, namely the magnetoelectric coupling. Recent investigations of ferroelectric and ferromagnetic thin films at a finer scale recently revealed that their domain walls have their own set of unique properties different from those of the domains, which can be controlled by external fields, opening the way to exploit these much localized functionalities to build true nanodevices. Understanding the domain wall properties, in particular their transport characteristics and associated physics, is essential in order to exploit their vast device potential, which could in the long term lead to truly reconfigurable nanoelectronics, where fully operational nanodevice circuits could be written, used and erased indefinitely.***This research program will therefore study the fascinating properties of epitaxial thin films that do exhibit multiferroic and magnetoelectric properties at room temperature. In particular it will build on the body of work on the few epitaxial room temperature multiferroic thin films synthesized and investigated during the last 5 years, which exhibit a particular kind of domain walls, namely boundaries between in-plane orientation domains. The domain walls properties of these specific films will be studied, with a very strong emphasis on the local properties of the unique kind of domain walls they exhibit, which have never been studied before.***Further building on the expertise acquired in growing epitaxial films of complex multiferroic films, the epitaxial growth of composite magnetoelectric thin films with various architecture will also be investigated and proof-of-concept devices will be fabricated using the room temperature magnetoelectric films produced.***Finally, extending the knowledge acquired in epitaxial growth to a further class of materials, the epitaxial growth of multiferroic or magnetoelectric hybrid organic-inorganic materials, will be achieved and their properties, beyond photovoltaic features including ferroelectric, piezoelectric, magnetic, possibly thermoelectric nt for students and HQP in general, at the leading edge of today's research in the field.
这项研究的重点是表现出同时具有磁性和铁电特性的多效材料。尽管在室温下仍然很少有广泛的研究领域,但仍然需要更深入地了解它们的性质,尤其是铁电和磁性性能之间的耦合,即磁电耦合。最近对铁电和铁磁性薄膜进行的最新研究最近显示,他们的域壁具有与域不同的独特属性,可以通过外部磁场来控制,这为这些众多局部功能开辟了道路,构建真实的纳米版。了解域壁性能,尤其是它们的运输特性和相关的物理学,对于利用其巨大的设备潜力至关重要,从长远来看,这可能会导致真正可重新配置的纳米电子学,可以在其中编写,使用,并使用完全操作的纳米电视电路。 ***因此,该研究计划将研究在室温下确实表现出多效和磁电特性的外延薄膜的迷人性能。特别是,它将建立在过去5年中综合和研究的几个外延室温多种薄膜上的工作体内,该薄膜表现出特定的域壁,即平面定向域之间的边界。将研究这些特定膜的域墙属性,非常重视它们展示的独特域壁的本地特性,这些壁壁从未进行过。还将研究复杂多表情膜的膜,具有各种体系结构的复合磁电薄膜的外延生长,并将使用室温磁电膜制造,并将概念验证设备制造。增长了进一步的材料,将实现多效或磁性混合有机无机材料的外延生长,其性能以及它们的性能,除了光伏特征之外当今研究的领先优势。
