Here we investigated the field emission effect in nanoconstrictions made on the basis of the microwire in glass insulation. Glass-coated single-crystal microwires of Bi and Bi-Sb were fabricated by the Ulitovsky method; then, using the technique of local laser heating, nanoconstrictions were made. We investigated the field electron emission obtained in Bi and Bi0.97Sb0.03 nanoconstrictions at various temperatures and different potentials on the gate electrode. We observed a change in the field emitted electron current depending on the potential on the gate electrode. This difference ΔI/I=0.26 is a manifestation of the change in the microwire tip potential due to the electric field effect.
