ZERNQV, DMITRII VLADIMIROVICH (Electronics Expert) 



D. V. Zernov was born March 20, 1907. Upon graduation in 

 1930 from Moscow University, he worked at the AU-Union 

 Electro-Technical Institute until 1934. From 1932 to 1938, he 

 taught at the Moscow Institute of Transport Engineers. From 

 1936 to 1939, he worked at the Scientific Research Institute of 

 Cinematography and Photography. In 1939, he worked at the 

 Institute of Automation and Telemechanics of the U.S.S.R. Aca- 

 demy of Sciences, and in 1953 at the U.S.S.R. Academy of Sci- 

 ences Institute of Radiotechnology and Electronics. He was 

 elected, in 1953, a Corresponding Member of the U.S.S.R. Aca- 

 demy of Sciences. 



In the early 1930' s, Zernov was the first in the Soviet Union 

 to construct sodium vapor fluorescent lamps. Under his leader- 

 ship a television system with a large multi -grain screen was 

 developed, for which he created a multi -contact, electron-beam 

 commutator. In later years, Zernov continued work on the im- 

 provement and investigation of electron-beam devices of the 

 commutator type. He studied electronic emission of thin di- 

 electric layers under the influence of a field of a positive sur- 

 face charge which is formed by electron bombardment.
