Abstract
Copper sulfide nanowires of diameter of ~ 1.2 nm were grown within the crystal channels of Na-4 mica. These consist of both CuS and Cu2S strands. Electrical conduction over the temperature range of 130-300 K was characterized by very low activation energies in the range of 0.008-0.004 eV. The nanocomposites exhibit giant dielectric permittivity of ~ 1617 which has been explained on the basis of one-dimensional metallic nanowires as predicted by the Gorkov-Eliashberg [Sov. Phys. JETP 21, 940 (1965) ] and Rice-Bernasconi [Phys. Rev. Lett. 29, 113 (1972) ] models.
