Biography
Daniel Chee Tsui was born on February 28, 1939, in Baofeng County, China. He went from Pui Ching Middle School and Clementi Secondary School to Augustana College, Boston University, and finally the University of Chicago, where he specialized in physics. Tsui later became a Professor of Electrical Engineering, emeritus, at Princeton University, and became a top researcher in the electrical properties of thin films and semiconductor microstructures.
Tsui's groundbreaking work in solid-state physics led to his most important scientific achievement: discovering a new type of quantum fluid with fractionally charged excitations. This finding changed the way people understand quantum mechanics and condensed matter physics. Working with Robert B. Laughlin and Horst L. Störmer, Tsui discovered this quantum phenomenon, which was later explained through theories on the fractional quantum Hall effect.
Tsui received many honors for his work. In 1998, he was awarded the Nobel Prize in Physics, sharing it with his colleagues for their quantum fluid discovery. In the same year, he received the Benjamin Franklin Medal in Physics. Earlier, he won the Oliver E. Buckley Condensed Matter Prize in 1984, and he became a Fellow of the American Physical Society in 1985 and the American Association for the Advancement of Science.
Tsui's academic achievements earned him honorary doctorates from several institutions, including the University of Hong Kong, Peking University in 2012, and the Chinese University of Hong Kong. In 2009, his contributions to American society were recognized with the Great Immigrants Award, highlighting his role as an immigrant scientist who advanced knowledge and innovation in the United States. Throughout his career, Tsui has focused on research that connects theoretical physics with practical applications in semiconductor technology.
Before Fame
Growing up in China during a time of major political and social change, Tsui received a solid education in math and science. His journey from Chinese secondary schools to American universities was part of a larger movement of skilled scientists looking for advanced research opportunities after World War II.
Condensed matter physics was booming during Tsui's early career years. Advances in semiconductor technology and quantum mechanics were opening up new areas of research, especially in understanding the electrical properties of materials on a tiny scale. This scientific setting was ideal for Tsui's later groundbreaking discoveries in quantum physics.
