项目摘要

Research in the field of functional materials plays an important role in solving current and future global challenges related to societal problems concerning energy, environment and health. This proposal describes a comprehensive research program that explores the frontiers of an important class of functional materials, the ferroic materials, including the piezoelectrics (which convert mechanical energy into electrical energy, and vice versa), ferroelectrics (with switchable polarization) and magnetoelectrics (with interacting polarization and magnetization). These materials are useful in a vast range of industrial and commercial applications, e.g. as nonvolatile random-access memory devices in future computers, 'smart' sensors and actuators for active control of vibration or noise, high-resolution ultrasonic transducers for medical imaging, bio-sensing or energy harvesting. The intriguing ferroic properties, which are essential to these applications, result from the microscopic and nanoscopic crystal chemistry of materials, i.e. the nature of constituent ions and chemical bonding, the atomic and spin arrangements, and the related phase components and transitions. Therefore, understanding the relationship between nanostructure and macroscopic functional properties is central to ferroic materials research, and it is along this line that our research program is established.

功能材料领域的研究在解决与能源，环境和健康有关的社会问题有关的当前和未来的全球挑战方面起着重要作用。该提案描述了一项全面的研究计划，该计划探讨了重要的功能材料的前沿，包括压电（将机械能将机械能转换为电能，反之亦然），铁电（具有可切换极化）和磁电（具有相互作用和磁性的磁性）的边界。这些材料在大量工业和商业应用中很有用，例如作为未来计算机中的非挥发性随机存储设备，“智能”传感器和执行器可积极控制振动或噪声，高分辨率超声传感器用于医学成像，生物感应或能量收集。对这些应用至关重要的有趣铁质特性是由材料的显微镜和纳米晶体化学产生的，即成分离子和化学键合的性质，原子和自旋布置以及相关的相分量和过渡。因此，了解纳米结构与宏观功能性能之间的关系对于铁罗材料研究是至关重要的，并且沿着这条线建立了我们的研究计划。
