Abstract :
X-ray diffraction studies of Cu6AsS5I crystals grown using the chemical vapor transport method are performed. Complex electrical conductivity, impedance, dielectric permittivity, and electrical modulus of Cu6AsS5I 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 Cu6AsS5I from the frequency and temperature dependencies of electrical properties.
