Annotation
The main purposes of the research were the studying of the dependence of the current strength on voltage and temperature, the effect of doping time on the conductivity and photoconductivity of models of mature doped cotton fibers (CF) “Komolot-79” doped with KMnO4. The study was performed in the temperature (298 to 360 K) and voltage range (0 to 100 V). It was observed that the CF model doped with KMnO4 was significantly higher than the non- doped model. It was found that the current flowing from a CF model doped with KMnO4 follows the Ohm’s law. It was also analyzed that the development of photoconductivity under the influence of ultraviolet radiation of a model of CF doped with KMnO4 indicates that the photoconductivity is mainly associated with the development of a network electron-hole pair. The obtained results revealed the activation energy of the deep layer formed by doping CF with KMnO4.
