Abstract Photostimulated two-level switchings of a vertical current are observed in thin (L=200 Å) amorphous silicon layers with a submicron electrical contact area (S=0.5×0.5 mm). The switching frequency increases with the photon flux. The conductivity fluctuations are explained on the basis of a microscopic nonlocal Staebler-Wronski effect. It is shown that the elementary event of formation of a metastable defect is accompanied by a reorganization of the system over a long distance of ∼2500 Å.
