ELECTRICAL BEHAVIOR OF A Cu2Fe0.4Co0.6SnS4 CERAMIC

The solid solutions Cu2Fe1-X CoX SnS4, with stannite-type structure are stable up to about 800°C. The electrical properties of the Cu2Fe0.4Co0.6SnS4 ceramic were investigated by complex impedance. The real and imaginary dielectric permittivity dependence with the temperature were measured between 10...
