Alternating-current conduction in thick refractory boride films

  • Published:
Soviet Powder Metallurgy and Metal Ceramics Aims and scope

Conclusions

A study was made for the first time of the electrical resistance of thick barium, lanthanum, and nickel boride films in the frequency range 500 Hz–200 MHz. Up to 500 kHz the resistance of the films was independent of frequency. In the range 30–200 MHz the resistance of low-resistance films grew with frequency, and that of high-resistance films fell. Such behavior of films may be due to two mechanisms of electrical conduction — jump conduction over localized states in the vicinity of the Fermi level and metallic conduction — being superimposed on one another.
