Qısa məlumat

As a result of studying the current -voltage characteristics of Te GexAsyTe100-x-y -AI structure at a negative potential of the tellurium electrode, it have been found tha at applied electric field voltage exceeding 5.10(4) V/cm, the current -voltage dependence has the N -shape and exhibits instability in the form of irregular current oscillations. The observed features of electric charge transfer under the influence of strong electric fields are interpreted taking into account the topological features of amorphous chalcogenides and the role of U--centers in the process of generation and recombination of electric charge carriers in the studied structure.
