Enhanced Coulomb repulsion screening around light element nuclei is achieved by way of utilizing electromagnetic (EM) radiation to induce plasmon oscillations in target structures (e.g., nanoparticles) in a way that produces high density electron clouds in localized regions of the target structures, thereby generating charge density variations around light element atoms located in the localized regions. Each target structure includes an electrically conductive body including light elements (e.g., a metal hydride/deuteride/tritide) that is configured to undergo plasmon oscillations in response to the applied EM radiation. The induced oscillations causes free electrons to converge in the localized region, thereby producing transient high electron charge density levels that enhance Coulomb repulsion screening around light element (e.g., deuterium) atoms located in the localized regions. Various systems capable of implementing enhanced Coulomb repulsion screening are described, and various nanostructure compositions and configurations are disclosed that serve to further enhance fusion reaction rates.

Enhanced electron screening through plasmon oscillations

A hot carrier photodetector has been developed that absorbs approximately 80% of broadband infrared radiation by using a planar nanoscale back metal contact to silicon. Based on the principles of the hot carriers generation in ultrathin metal films, silicon-based CMOS image sensors are developed which operate in the IR diapason. The device uses absorption in an ultrathin metallic nanostructure to generate therein a non-equilibrium electron distribution which subsequently is injected into the silicon material via a Schottky contact at the Si body, thus generating a photoresponse to an incident IR radiation. A pixeled array including interconnected hot carriers metallic nanostructured cell(s) and traditional RGB elements is envisioned to enable RGB-IR imaging from a single silicon based wafer.

Silicon-based photodetectors with expanded bandwidth

Enhanced Coulomb repulsion (electron) screening around light element nuclei is achieved by way of utilizing target structures (e.g., nanoparticles) that undergo plasmon oscillation when subjected to electromagnetic (EM) radiation, whereby transient high density electron clouds are produced in localized regions of the target structures during each plasmon oscillation cycle. Each target structure includes an integral body composed of an electrically conductive material that contains light element atoms (e.g., metal hydrides, metal deuterides or metal tritides). The integral body is also configured (i.e., shaped/sized) to undergo plasmon oscillations in response to the applied EM radiation such that the transient high density electron clouds are formed during each plasmon oscillation cycle, whereby brief but significantly elevated charge density variations are generated around light element (e.g., deuterium) atoms located in the localized regions, thereby enhancing Coulomb repulsion screening to enhance nuclear fusion reaction rates. Various target structure compositions and configurations are disclosed.
