Abstract
The effect of electron doping in LuxMn1-xS and cationic vacancies in Mn0.9S manganese sulfide on the formation of phonon modes of vibration, the type of conductivity, and the impedance characteristics is studied. The IR spectra in the frequency range 450-7500 cm−1, the I-V in the temperature range 300-500 K, and the impedance in the frequency range 102-106 Hz were measured. The qualitative difference in the temperature behavior of the impedance, the activation character of the relaxation time, and the change in the activation energy of the impurity conductivity in LuxMn1-xS at high temperatures are found.
