Focused electron beam induced multi-tip deposition for energy harvesting fromthe green-house radiaton. — •Koops Hans Wilfried Peter — Ernst Ludwig Strasse 16, Ober-Ramstadt, Germany
A cross -lines grid with 0,5 µm cell-width is proposed to harvest IR radiation from the green house gases in the earth atmosphere. According to NASA-measurements 340 W/m2 reach the earth in the IR-regime. A nanogranular Pt/C material can be used in a detector-matrix to harvest this energy, by collecting IR quanta with nanocrystalline Pt/C compound material in form of electron-hole Bosons. Very large numbers of Bosons can be stored in such energy layers. Applying a field gadient allows to move the Bosons to the end of the material layer, where the Bosons release an electron each, and the resulting hole can form a new Boson again. Electrons are emitted in a coherent fashion. The small-area experiment shall proove the principle of the energy harvesting capability. Large areas of collector fields shall follow, built with the principle of glass coating machines with massive parallel ion beam sources to deposit the Pt/C absorber structure layers.
