Abstract:
A method for generating electrically conducting, semiconducting, and/or non-conducting structures in two or three dimensions in a composite matrix, the method comprising:applying to each separate layer an electric field with given field strength and/or characteristics adapted to the specific response of a material to the energy supplied by the field, wherein the matrix comprises one or more materials respectively provided in one or more spatially separate and homogenous material structures, wherein the materials in response to the supply of energy can undergo specific physical and/or chemical changes of state which cause transition from an electrically non-conducting state to an electrically conducting and/or semiconducting state or vice versa, or a change in the electrically conduction mode of the material, and wherein each material structure is made in the form of a thin layer; modulating in each case the fields spatially according to a determined protocol which represents a predetermined pattern of electrically conducting and/or semiconducting structures in the relevant material structure, whereby in the layers in response to the energy supplied by the field two-dimensional electrically conducting and/or semiconducting structures are generated with the pattern predetermined by the protocol; and optionally providing two or more layers in a stacked configuration, such that the composite matrix formed by laminating separate adjacent layers is provided with electrically conducting or semiconducting structures in three dimensions.
