Alfred Y. Cho

Alfred Yi Cho , Chinese 卓 以 和 , (born July 10, 1937 in Beijing ) is a Chinese-American electrical engineer.

Cho went to Hong Kong in 1949 , where he attended school. He studied electrical engineering at the University of Illinois , where he received his master's degree in 1961 and his doctorate in 1968. In between he was from 1961 at the Ion Physics Corporation in Burlington (Massachusetts) and from 1962 at the TRW Space Technology Laboratories in Redondo Beach , where he researched high-intensity ion beams. In 1968 he went to Bell Laboratories , where he became department head in 1984 and in 1987 head of the Materials Processing Research Lab. From 1990 he was director of semiconductor research there.

Cho is considered to be one of the inventors of molecular beam epitaxy (MBE), which he developed with John R. Arthur at Bell Labs in the late 1960s . With Federico Capasso , he also developed the quantum cascade laser at Bell Labs in the 1990s. He has published over 400 papers and holds 46 patents (2010).

His numerous prizes include the IEEE Medal of Honor (1993), the Elliott Cresson Medal of the Franklin Institute (1995), the Heinrich Welker Medal from Siemens (1986), the American Physical Society International Prize for New Materials (1982), the Morris E. Liebmann Award from the IEEE and in 1994 the National Medal of Science and the Von Hippel Award . In 2015 he was awarded the Rumford Prize . He is a member of the National Academy of Sciences , the American Academy of Arts and Sciences , the National Academy of Engineering and the American Philosophical Society as well as a Fellow of the American Physical Society and the IEEE. In 2009 he was inducted into the National Inventors Hall of Fame .

Cho is married and has one son and three daughters.
