Effect of carbon vacancies on the electric resistivity of nonstoichiometric VC$_y$ vanadium carbide
A. I. Gusev Institute of Solid State Chemistry, Urals Branch of the Russian Academy of Sciences
Abstract:
The influence of the temperature, concentration, and distribution of structure vacancies of the carbon sublattice on the electric resistivity ρ of nonstoichiometric VC y vanadium carbide (0.66 ≤ y ≤ 0.875) has been studied in the temperature range of 300–1200 K. The symmetry and structure characteristics of the ordered V6C5 and V8C7 phases formed owing to low-temperature annealing on various sections of the homogeneity region of the VC y carbide. The dependence of the residual electric resistivity on the content of the disordered vanadium carbide is explained by the atom-vacancy interaction and the change in the carrier concentration in the homogeneity region of VC y .
