Emeritus and Research Professor Tai-Chang Chiang of the University of Illinois at Urbana-Champaign has been elected by the Academia Sinica to its 2016 class of Academicians. He is among 22 scholars across all academic disciplines to receive this high honor this year. Academia Sinica is the national academy of Taiwan. Former Academicians in the mathematics and physics division include Nobel laureates T.D. Lee, C.N. Yang, Sam Ting, and Daniel Tsui.

Over the course of his career, Chiang has made lasting contributions to condensed matter physics, surface science, and synchrotron radiation research, including several truly groundbreaking findings. He has authored about 300 journal articles, and his work has been cited more than 8,500 times.

Chiang’s work on precision electron spectroscopy and structural determination has led to important advances in the physics of electrons, lattice structures, and phonons and their mutual interactions in solids, at surfaces, in films, and at the nanoscale.

His landmark research on thin films and quantum well spectroscopy has received international recognition. Specifically, Chiang showed that quantum well states could be observed in films as thick as tens of atomic layers, debunking the notion that only semiconductor substrates could support quantum well states.

Another important breakthrough for Chiang was the making of atomically uniform films for thicknesses over a hundred atomic layers. This work again received international attention. Chiang went on to elucidate the properties of the surface, bulk, quantum well, multilayer, and superlattice electronic states. The accumulated work is a tour-de-force demonstration of quantum-state control through nanoscale engineering of film structures.

Chiang has since broadened his work to include ultrathin films of 3D topological materials, with a focus on the topological properties in the thin film (2D) limit.

Chiang is the recipient of numerous recognitions, including the 2015 Davisson-Germer Prize in Atomic or Surface Physics, sponsored by the American Physical Society (APS). He received the Xerox Award for Faculty Research (1985), the NSF Presidential Young Investigator Award (1984-89), and the IBM Faculty Development Award (1984-5). He is a Fellow of the APS.

Chiang’s professional service is likewise noteworthy. He served as head of the Solid State Sciences and Materials Chemistry Program from 1991 to 2006. He was associate director of the Frederick Seitz Materials Research Laboratory from 1999 to 2006. From 2003 to 2008, he chaired the Board of Governors for UNICAT at the Advanced Photon Source, Argonne National Laboratory. From 2010 to 2014, he served as the scientific director of the University of Wisconsin-Madison Synchrotron Radiation Center. He was appointed Chair Professor at the National Chiao-Tung University (2013-16); Honorary Chair at National Tsing Hua University (2008-11); and Distinguished Chair at National Taiwan University (2007-10 and 2015-present). He is currently a visiting professor at Tokyo University.

Chiang received a bachelor’s degree in physics from the National Taiwan University in 1971 and a doctoral degree in physics from the University of California, Berkeley in 1978. He held a postdoctoral appointment at the IBM T.J. Watson Research Center in Yorktown Heights from 1978 to 1980, before he joined the faculty at Physics Illinois in 1980.

Recent News

Quantum information science has been called the next technological “space race.” And the University of Illinois is positioning itself to be at the forefront of that race. In November, the U of I pledged $15 million for the formation of the Illinois Quantum Information Science and Technology Center (or IQUIST). Two of the leading experts in the field, Illinois physics professors Brian DeMarco and Paul Kwiat join the show to discuss its vast future applications. Both professors represented the University of Illinois at the first ever Chicago Quantum Summit in November. DeMarco was invited to the Advancing American Leadership in Quantum Information Science Summit at the White House last fall.

Anderson was a strong believer in education and his philanthropy and volunteerism reflected this. He was dedicated to providing educational opportunities to others.  He served as a Life Trustee at Rensselaer Polytechnic Institute and was a trustee of the Norwalk Community College Foundation. He was a member of the Visiting Committee of the University of Illinois College of Engineering, where he was inducted into their Engineering Hall of Fame in 2010. He and his wife Lois sponsored the Distance Learning Center at Illinois and endowed scholarships at R.P.I., Norwalk Community College and Northwestern University.

As the chair of the NASA Fundamental Physical Sciences  Review Board, which has oversight responsibility for the recently launched Cold Atom Laboratory (CAL), Professor Brian DeMarco plays a seminal role in the "Coolest Experiment in the Universe," taking place on the International Space Station. DeMarco is featured in the video released in conjunction with this press release. The ultra-cold-atom experiment will study a Bose-Einstein condensate in space to uncover a new understanding of its properties and interactions at a temperature barely above absolute zero.

Professor Peter Abbamonte has been named the Fox Family Professor in Engineering at the University of Illinois at Urbana-Champaign. Named faculty appointments signify a distinction beyond that of professorial rank, recognizing distinguished scholars for their prominence in research, teaching, and service.
