Investigation of electrophysical properties of allotropic modifications of carbon in the range of temperatures 140–400 K

Abstract

The paper presents the results of the investigation allotropic modifications of carbon (coal, graphite, fullerenes, CNTs Dependences of conductivity on the field frequency in the temperature range 140-400 •K are presented. The characteristic features associated with the structure and types of hybridization are revealed. Calculation of the activation energy of carriers was performed.
