Academician Liang Junwu, the founder of early semiconductor silicon materials in my country, passed away

　　On June 24, the Institute of Semiconductors of the Chinese Academy of Sciences issued an obituary: Mr. Liang Junwu, an academician of the Chinese Academy of Engineering, a researcher of the Institute of Semiconductors of the Chinese Academy of Sciences, and a famous semiconductor materials scientist in my country, was ineffective due to illness. Unfortunately, he died in Beijing at 17:00 on June 23, 2022. 89 years old.

　　Academician Liang Junwu was born on September 18, 1933 in Wuhan, Hubei, and was elected as an academician of the Chinese Academy of Engineering in 1997.

He has successively won the second prize for scientific and technological achievements of the State Science and Technology Commission and the second prize for new products, one third prize for national scientific and technological progress, three first prizes for major achievements and scientific and technological progress of the Chinese Academy of Sciences, and four second prizes. A total of more than 20 scientific and technological awards such as the second prize of scientific and technological progress.

　　Academician Liang Junwu has been engaged in the scientific research of semiconductor materials for more than 60 years and is the founder of the early semiconductor silicon materials in my country.

In the 1960s, the key technology of melting silicon in the high-purity area was solved; in 1964, GaAs liquid phase epitaxy materials for room temperature lasers were prepared; High-quality silicon region melting single crystal with carbon and oxygen controllable amount; pioneered nitrogen-doped neutron transmutation silicon single crystal in the 1980s, which solved the problem of the integrity and uniformity of silicon wafers; in the early 1990s, researched MOCVD growth of superlattice quantum Well materials, in terms of crystal integrity, electrical properties and superlattice structure control, have advanced Chinese superlattice quantum well materials to a practical level; he also plays an active role in the research and industrialization of polysilicon for solar cells.
