Laboratory of "Radiation physics of Disordered Solids"

Head of Laboratory: Dr.in phys.-math., prof. O.A.Samadov

Main scientific directions: Produce of disordered solid solutions by alloying and radiation influence methods and study of their dielectric and electric impedance spectrum.

Main scientific achievements: TlInS2 In crystal it has been observed anomalies in temperature dependencies of dielectric permittivity and loss-angle tangent at more than 300K temperature (at paraelectric phase). It has been shown that, the boundary of high frequency region in (Z″−Z′) complex plane diagram of γ-irradiated TlInS2 crystal, slips towards frequency decrease with increase of irradiation dose. The conductivity mechanism in both irradiated and nonirradiated TlInS2 crystal has been determined (electron and at high temperatures – ion). Polarization type: electron and ion-relaxation polarization. Equivalent scheme has been established.
