Electrically conducting doped polyacetylene film exhibiting n-type electrical conductivity and method of preparing same |
摘要 |
Electrically conducting organic polymeric film material exhibiting a preselected room temperature n-type electrical conductivity ranging from that characteristic of semiconductor behavior to that characteristic of metallic behavior, is prepared by controlled electron donor doping of a polycrystalline film of polyacetylene with a metal dopant whose Pauling electronegativity value is no greater than 1.6. Preferred metal dopants are the alkali metals. The procedure may be employed in preparing polyacetylene film with a p-n junction formed by two adjacent portions of the film respectively provided wth p-type and n-type electrical conductivities.
