Abstract: Flexible electronics was listed by Science as one of the top 10 technological breakthroughs in 2000. Applications in flexible electronics are very broad, much broader than the chip-based rigid ones due to their unique properties and special utility.   However, flexible electronics have been traditionally used to mainly address low-speed applications, such as displays, biomedical applications, sensors, etc. For microwave electronics applications, such as wireless communication and surveillance systems, one has to use rigid chip-based electronics instead. In this talk, I will present the microwave flexible electronics that were developed over the last decade. Examples of both flexible active and flexible passive components will be shown, followed by flexible MIC examples. A future prospect of microwave flexible electronics will be outlined.

The semiconductor heterostructure is one of the most important inventions in the last century that has deeply impacted human society. To form heterostructures using bulk semiconductors, lattice match is an essential requirement. We have successfully overcome the lattice-mismatch challenge. In this talk, I will present exemplary applications of the novel heterostructure approach to electronics, optoelectronics, and energy, following a brief discussion of the physical mechanisms. Future research directions will be discussed at the end.

Biography: Zhenqiang (Jack) Ma received his B.S. degree in applied physics and B.E. degree in electrical engineering from Tsinghua University in Beijing, China in 1991. He received his M.S. degree in nuclear science and M.S.E. degree in electrical engineering from the University of Michigan, Ann Arbor in 1997, and the Ph.D. degree in electrical engineering from the University of Michigan, Ann Arbor in 2001. From 2001-2002, he was a member of the R&D team at Conexant Systems and later its spin-off, Jazz Semiconductor (now TowerJazz), in Newport Beach, CA. In 2002, he left Jazz to join the faculty of University of Wisconsin–Madison as an assistant professor in the Department of Electrical and Computer Engineering. He is now a Lynn H. Matthias Professor in Engineering and a Vilas Distinguished Achievement Professor with affiliated appointments in four other departments and research institutes in engineering and medical school. His current interdisciplinary research covers electrical engineering, materials science and engineering, and biomedical engineering. His present research focuses on the materials, physics and device applications of lattice-mismatched 3D-semiconductor heterostructures, microwave flexible electronics, and bioelectronics. He is the author or co-author of about 500 technical papers and book chapters related to his research and holds over 70 US, foreign and international patents. He is a recipient of PECASE. He is a fellow of AAAS, AIMBE, APS, IEEE, NAI and OSA.
