Abstract: The semiconductor heterostructure is one of the most important inventions in the last century that has deeply impacted human society. To form heterostructures using 3D semiconductors, lattice mismatch is an essential requirement. Despite the huge success of lattice-matched heterostructures, forming heterostructures between two arbitrary types of semiconductors unrestricted by lattice match, which is expected to open a much larger space for materials engineering and enable much broader applications than the ones based on lattice matched ones, has been sought after and attempted for over six decades without success. In this talk, I will present a philosophically nanoscale-engineered semiconductor interface formation approach that allows the successful formation of large lattice-mismatched 3D semiconductor heterostructures. Following the discussion of the physical mechanisms, exemplary applications of the novel heterostructure approach to electronics, optoelectronics, and energy will be presented. An overview of my interdisciplinary research program will be given at the beginning of the talk and future 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 over 480 peer-reviewed 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.
