ELECTROPHYSICAL PROPERTIES OF -PBN6 WHISKERS

The paper describes the methods of dark conductivity, photoconductivity, thermally stimulated currents and thermally stimulated capacitor discharge that were developed to study electrophysical properties of whisker crystals of lead β-azide (WC β -PbN6) – initiating explosive compound, – such as: changing dark conductivity of deformed WC βPbN6; energy of electron and hole centers distributed in the forbidden band; estimation of activation energy in the temperature range 298 ÷ 353 K, which amounted to 0.52 ± 0.04 EV, in the temperature range 366 ÷ 433 K, with 1.04 ± 0.04 EV and 1.56 ± 0.04 EV respectively at higher temperatures. A possible type of disorder responsible for the observed changes in activation energies is discussed.
