Frenkel has written numerous books in several areas of physics and was a member of the Soviet Academy of Sciences since 1929.

Best known are his contributions to solid state physics. According to him, the Frenkel defect, the ' Frenkel Kontorowa model ' and the Frenkel exciton are named. Also, the terms and phonon tunneling effect, which he used in 1932 for the first time in his book "Wave Mechanics, Elementary Theory", go back to him.
