Abstract in different language: The paper studies static V-A characteristics of very thin conducting fibers. The aim is to find the presence of a negative differential resistance in the characteristic. It is shown that this effect can be found only supposing that the nonlinear dependence of the metal conductivity on temperature is taken into account, i.e., the dependence including the quadratic term. Finally the system of fibers is studied with a proper statistical distribution of their conductivity. The parametric study was performed. The resulting V-A characteristics can be compared with the characteristic measured on the fabricated metal-insulator-metal structure. This comparison shows that the described model can serve as a good way to determine the V-A characteristics of MIM structures.
