Abstract: A detailed review of experimental and theoretical studies of secondary electron emission (SEE) at low electron energies performed in the past has been given in this paper. It is shown that some present-day authors’ statement on increase of the SEE yield up to unity while the primary electron energy tends to zero does not have sufficient theoretical justification and is inconsistent with the numerous experimental data obtained for various materials.
