In this paper we consider the case of inhomogeneous generation of charge carriers in a sample under bulk irradiation, as well as the case of near-surface generation of charge carriers in order to confirm or disprove the statement that the formation of a plateau on time-of-flight curves is associated with the establishment of quasi-equilibrium transport. A theoretical model of this process was constructed. In accordance with the theoretical model, a calculation program was compiled in the MathCad package and calculations were made. As a result of comparison of the transition current curves in a polar molecular-doped polymer for near-surface and bulk (nonuniform) charge carrier generation, it has been established that the transformation of a horizontal plateau expected in quasi-equilibrium transport conditions on the first of them to the curve predicted by the theory of diffusion and drift did not occur . Which refutes the proposed theory. On the basis of the work done, articles were written and at the moment are in the press, which will be published in the collection of E.V. Armensky [1], and also in the journal "Polymer Science" [2], cited by the index of Web of Science and Scopus.
