1. A method of forming a desired pattern of transparent electrical conductors on a base, comprising the steps of:

  • selecting a first material oxidizable to form a transparent insulating material;

    selecting a modifying material combinable with said first material to form a second material, wherein said second material is oxidizable to form a transparent electrical conductor material;

    forming a layer of said modifying material on said base in a pattern conforming to said desired pattern of transparent electrical conductors;

    forming a layer of said first material adjacent said layer of modifying material on said base;

    diffusing said modifying material into said first material to form said second material; and

    oxidzing said first and second materials to form a substantially continuous layer of oxidized material having a transparent conductor region conforming to said desired pattern and a transparent insulator region.
