Alfred Yi Cho (Chinese :卓以和; pinyin :Zhuó Yǐhé; born July 10, 1937 [1] ) is the Adjunct Vice President of Semiconductor Research at Alcatel-Lucent's Bell Labs. He is known as the "father of molecular beam epitaxy"; a technique he developed at that facility in the late 1960s. He is also the co-inventor, with Federico Capasso of quantum cascade lasers at Bell Labs in 1994.

Chinese language family of languages

Chinese is a group of related, but in many cases not mutually intelligible, language varieties, forming the Sinitic branch of the Sino-Tibetan language family. Chinese is spoken by the Han majority and many minority ethnic groups in China. About 1.2 billion people speak some form of Chinese as their first language.

Hanyu Pinyin, often abbreviated to pinyin, is the official romanization system for Standard Chinese in mainland China and to some extent in Taiwan. It is often used to teach Standard Mandarin Chinese, which is normally written using Chinese characters. The system includes four diacritics denoting tones. Pinyin without tone marks is used to spell Chinese names and words in languages written with the Latin alphabet, and also in certain computer input methods to enter Chinese characters.

Bell Labs research and scientific development company

Nokia Bell Labs is an industrial research and scientific development company owned by Finnish company Nokia. Its headquarters are located in Murray Hill, New Jersey. Other laboratories are located around the world. Bell Labs has its origins in the complex past of the Bell System.



Cho was born in Beijing. He went to Hong Kong in 1949 and had his secondary education in Pui Ching Middle School there. Cho holds B.S., M.S. and Ph.D. degrees in electrical engineering from the University of Illinois. He joined Bell Labs in 1968. He is a member of the National Academy of Sciences and the National Academy of Engineering, as well as a Fellow of the American Physical Society, the Institute of Electrical and Electronics Engineers, and the American Academy of Arts and Sciences.

Beijing Municipality in Peoples Republic of China

Beijing, formerly romanized as Peking, is the capital of the People's Republic of China, the world's third most populous city proper, and most populous capital city. The city, located in northern China, is governed as a municipality under the direct administration of central government with 16 urban, suburban, and rural districts. Beijing Municipality is surrounded by Hebei Province with the exception of neighboring Tianjin Municipality to the southeast; together the three divisions form the Jingjinji metropolitan region and the national capital region of China.

In June 2007 he was honoured with the U.S. National Medal of Technology, the highest honor awarded by the President of the United States for technological innovation. [2]

Cho received the award for his contributions to the invention of molecular beam epitaxy (MBE) and his work to commercialize the process.

He already has many awards to his name, including: the American Physical Society's International Prize for New Materials in 1982, the Solid State Science and Technology Medal of the Electrochemical Society in 1987, the World Materials Congress Award of ASM International in 1988, the Gaede-Langmuir Award of the American Vacuum Society in 1988, the IRI Achievement Award of the Industrial Research Institute in 1988, [3] the New Jersey Governor's Thomas Alva Edison Science Award in 1990, the International Crystal Growth Award of the American Association for Crystal Growth in 1990, the National Medal of Science in 1993, [4] the Von Hippel Award of the Materials Research Society in 1994, the Elliott Cresson Medal of the Franklin Institute in 1995, the IEEE Medal of Honor in 1994, and the Computers & Communications Prize of the C&C Foundation, Japan in 1995.In 2009, he was inducted into the National Inventors Hall of Fame.

IRI Achievement Award

The IRI Achievement Award, established by the Industrial Research Institute (IRI) in 1973, is awarded "to honor outstanding accomplishment in individual creativity and innovation that contributes broadly to the development of industry and to the benefit of society." The recipient is first nominated by an IRI member organization for his or her invention, innovation, or process improvement, and then voted on by a nine-member Awards Committee, led by the immediate past-chairman of IRI's Board of Directors.

The Industrial Research Institute, Inc. (IRI) is a nonprofit association based in Arlington, Virginia. The stated mission of IRI, which was founded by the National Research Council in 1938, is “to enhance the effectiveness of technological innovation by networking the world's best practitioners and thought leaders to seek, share, learn, and create”. IRI is a nonpartisan, membership-based organization that brings leaders of R&D together to discover and share best practices in the management of technological innovation.

National Medal of Science award

The National Medal of Science is an honor bestowed by the President of the United States to individuals in science and engineering who have made important contributions to the advancement of knowledge in the fields of behavioral and social sciences, biology, chemistry, engineering, mathematics and physics. The twelve member presidential Committee on the National Medal of Science is responsible for selecting award recipients and is administered by the National Science Foundation (NSF).

In 1985, Bell Labs became the first organization to be honoured with a U.S. Medal of Technology, awarded for “contributions over decades to modern communications systems.” Cho's honour marks the eighth time Bell Labs and its scientists have received the award.

Cho is married and has one son and three daughters.
