摘要：
Nonlinear current-voltage characteristics of Ta2O5 and Nb2O5 amorphous oxides are studied in the temperature range from 213 to 363 K. The data give an evidence for the polaron mechanism of charge transport in these materials. A theoretical treatment of data is presented that gives a critical hopping lenght and a critical index.
