Abstract:     An electronic fast switch for operation at room temperature utilizing uniform silicon nanoparticles (~1 nm with about 1 part per thousand exceeding 1 nm) between two conducting electrodes. The silicon nanoparticles, when on an n-type silicon substrate exhibit, at zero bias, a large differential conductance, approaching near full transparency. The conductance is observed after one of the electrode is first biased at a voltage in the range 3 to 5 eV (switching voltage), otherwise the device does not conduct (closed). A practical MOSFET switch of the invention includes the silicon nanoparticles in a body of the MOSFET, with the gate and substrate forming the two conducting electrodes. Electrodes may be realized by metal in other switches of the invention.
