Abstract: ACconductivityofthechalcopyritesystemsthin films in the
frequency range 80Hz-5MHz and temperature range 300-420K have been studied. The
obtained can be given by the

barrier height for each
composition, is calculated from the dielectric properties according to Guintini
equation.
Keywords and phrases: chalcopyrite, AC conductivity and chalcogenide.
