报告摘要：
A new world is being formed ?based on the technologies composed of artificial intelligence, ?Internet of Things (IoT), and robots. Especially, in the research ?fields of IoT and robotics systems, a device with mechanical ?flexibility can deliver more degrees of freedom as far as the design ?aspects are concerned. Therefore, the development of soft and flexible ?electronics becomes an important research direction for wearable and ?IoT devices. Due to the mechanical flexibility, polymer materials and ?thin metal foils are commonly used in the fabrication of flexible ?electronic systems. However, the reliability issue under practical ?operations hinders the applications of these flexible electronics, ?especially for those on polymer based substrates. This is attributed ?to a mismatch of thermal expansion coefficient between substrate and ?functional materials or low thermal and chemical endurance of polymers ?and organic materials. A lot of researchers are working hard and ?together to expand the applicability of current flexible devices. ?However, new pathway to flexible electronics can also be developed in ?parallel to provide more subtle solutions, thus in need of new ?platform to integrate functional materials with good thermal and ?chemical stabilities together with mechanical flexibility. In this ?research field, oxides can play an important role due to their ?intriguing functionalities and superior thermal and chemical ?stabilities. To deliver high-quality thin films or structures based on ?oxides, heteroepitaxy is essential. However, the lack of a suitable ?approach remains an obstacle for flexible oxide heteroepitaxy. van der ?Waals epitaxy (vdWE) involving two-dimensional layered materials can ?play a crucial role in the expansion of thin film epitaxy by ?overcoming the bottleneck of material combinations due to ?lattice/thermal matching conditions inherent to conventional epitaxy. ?In this study, we use a 2D material as the substrate. In this talk, we ?confine ourselves to the validity of vdWE of functional oxides on ?muscovite mica throughout this treatise. With such demonstrations, it ?is anticipated that MICAtronics, vdWE on mica, can reveal unusual ?properties and emergent phenomena in the realm of high-performance ?flexible device applications.

Professor Ying-Hao Chu ?received his PhD in the Department of Materials Science & ?Engineering from National Tsing-Hua University in 2004. Then, he ?joined University of California, Berkeley as a postdoc. In 2008, he ?acquired an assistant professorship in the Department of Materials ?Science & Engineering at National Chiao Tung University. He was ?promoted to an associate professor in 2015, and then he was promoted ?to a professor in 2018. From 2019, he was appointed as a distinguished ?professor. Since 2013, he has an adjunct position in institute of ?physics, Academia Sinica. In 2014 he started an adjunct position in ?the Department of Electrophysics, National Chiao Tung University. From ?2016 to 2018, he had the adjunct position in the Material and Chemical ?Research Laboratories, Industrial Technology Research Institute and ?the International College of Semiconductor Technology at National ?Chiao Tung university. From 2019, he has an appointment with ACS ?Applied Electronic Materials to be an associate editor. His research ?is highly focused on complex functional oxides and strongly correlated ?electron systems. He has extensive experience in the use of advanced ?characterization techniques to understand and manipulate functional ?oxide heterostructures, nanostructures, and interfaces. His current ?goal is try to create a pathway to use high quality oxide ?heteroepitaxy for soft transparent technology. Now, he is a pioneer ?with the most publication along this research direction. He has ?published more than 280 papers (Web of Science: >15000 citations, ?h-index=58; Google Scholar: >19000 citations, h-index=68) in ?academic journals, including Science series (2), Nature series (~25), ?PNAS (2), ACS Nano & Nano Letters (>25), Advanced (Energy or ?Functional) Materials (>20), Nano Energy (>5), Physical Review ?series (>25), Applied Physics Letters (~40).
