The scanning tunneling spectra of the trigonal bismuth surface are measured in the vicinity of the boundaries of terraces with a diatomic height. It is found that the tunneling spectrum of the planar surface begins to transform at a distance of 2-3 nm from the terrace boundaries, specific features that are characteristic of the planar surface far from the terrace boundaries disappear, and new peaks in the density of states are observed. An analysis of the behavior of the current-voltage characteristics has revealed that one-dimensional electronic systems with a width of the order of an interatomic distance with their own individual spectra are formed at the ends of the rows of the atomic planes.
