The effect of ion doping on the secondary emission characteristics of Mo, Pd and Pd-Ba alloy has been investigated. It was found that as a result of doping with low-energy barium ions, an intermetallic compound of the Pd-Ba type is formed in the near-surface Pd layer. The formation of a chemical compound between the substrate and the dopant contributes to a significant (3 times) increase in the secondary electron emission (SEE) coefficient. It is found that the samples of Pd and Pd-Ba after doping with a large dose of Ba+ ions have almost the same secondary emission parameters. Doping of Pd-Ba first with barium ions, then with oxygen ions with the energies of E0≤1 keV leads to a significant increase in the secondary electron emission (SEE) coefficient. In the case of implantation of Ba+ ions in Mo, formation of a chemical bond between the Ba and Mo atoms was not observed. Therefore, the emission efficiency in the ion-doped layer increases insignificantly (1.3 times) and the increase in the maximum value of the secondary electron emission coefficient σmax is explained by a decrease in the work function eφ.
