Beschreibung
Zusammenfassung:X-ray diffraction studies of Cu sub(6)AsS sub(5)I crystals grown using the chemical vapor transport method are performed. Complex electrical conductivity, impedance, dielectric permittivity, and electrical modulus of Cu sub(6)AsS sub(5)I crystal are studied in wide frequency range and temperature interval from 100 to 400 K. Different contributions into electrical conductivity spectra are revealed. Two phase transitions are confirmed for CusAsSgl from the frequency and temperature dependencies of electrical properties.
