演講題目:Ferroic Complex Oxides for Next-Generation Applications and Devices

演講時間:9月25日(三)下午2點

演講地點:工綜館228教室

演講摘要(Summary of Speech):

Complex-oxide materials possess a range of interesting properties and phenomena that make them candidates for next-generation devices and applications. But before these materials can be integrated into state-of-the-art devices, it is important to understand how to control and engineer their response in a deterministic manner. In this talk, we will discuss some of the state-of-the-art science, engineering, and utilization of complex ferroic materials and their potential for emergent order and phenomena that can enable new device function. We will explore the role of the epitaxial thin-film growth process and the use of epitaxial constraints to engineer a range of systems with special attention to ferroelectric, antiferroelectric, and relaxor materials – all of which are being considered for use in different types of next-generation logic, memory, tunable microwave communications, sensor/actuator, energy conversion, and other applications. In recent years, the use of epitaxial strain has enabled the production of model versions of these complicated materials and the subsequent deterministic study of field-dependent response. Here, we will investigate the potential of ferroelectric materials for non-volatile, ultra-low voltage memory and logic applications, the realization of multi-state/neuromorphic function, and even high energy density capacitive energy storage applications. We will try to introduce the listener to these complex materials and their potential for new applications – in effect working to motivate engineers to explore these materials. The discussion will range from the development of fundamental understanding of the physics that lies at the heart of the observed effects, to an illustration of routes to manipulate and control these effects, to the demonstration of rudimentary solid-state devices based on these materials.
