摘要:
The invention relates to nano granular materials (NGM) which has the extraordinary capability to conduct current in a 100 fold current density compared to high Tc superconductors by charges moving in form of Bosons produced by Bose-Einstein-Condensation (BEC) in overlapping excitonic surface orbital states at room temperature and has a light dependent conductivity. The material is disposed between electrically conductive connections and is a nano-crystalline composite material. The invention further relates to electrical components comprising NGM and methods and arrangements for making it by corpuscular -beam induced deposition applied to a substrate, using inorganic compounds being adsorbed on the surface of the substrate owing to their vapor pressure, and which render a crystalline conducting phase embedded in an inorganic insolating matrix enclosing the material.
