1. A method for generating electrically conducting, semiconducting, and non-conducting structures in three dimensions in a composite matrix comprising:

  • irradiating each material structure with a radiation of a given intensity or frequency characteristic adapted to the specific response of the material to energy supplied by the radiation, wherein the matrix comprises two or more of said materials provided in spatially separate and homogenous material structures and 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

    modulating the radiation spatially in each case according to a determined protocol which represents a predetermined pattern of electrically conducting and/or semiconducting structures in the relevant material structure, whereby in response to the energy supplied with the radiation two-dimensional electrically conducting and semiconducting structures are generated in the material structure with the pattern predetermined by the protocol, such that the composite matrix formed by laminating separate adjacent material structures with two-dimensional electrical conducting and semiconducting structures is provided with electrically conducting and semiconducting structures in three dimensions.
