Formation and electrical conductivity of low-dimensional copper structures in porous glass

Abstract

Metallic copper nanostructures were synthesized in porous glass membranes by reduction of twodimensional copper(II) oxide layers. The frequency and temperature dependences of the electrical conductivity, combined with X-ray diffraction data, evidence the fixation of a 2D copper layer on the walls of the through channels of the support. The possibility of formation of planar metallic structures depends on the degree of surface coverage by the oxide precursor. The amount of copper resulting from copper oxide reduction in porous glass determines its resistance to oxidation in air.
