The emission properties of the edge (110)W in presence of sub-monolayer coatings with Nb atoms were studied measuring the work function φ, Auger-electron spectroscopy and specters of total currents. It has been shown that in absence of Nb dilution in W, the work function decreases gradually at higher rate of niobium coating over the edge (110) W with its maximal value Δφ = 0.38 eV for a single monolayer. At dilution of Nb films upon annealing there was observed the extreme growth of Δφ. The maximal value of Δφ = 0.67 eV corresponds to the niobium coating rate of Ɵ ~ 0.7.
