Latest Patents

One of his latest patents is the Holography Transmission Electron Microscope. This groundbreaking device allows for electron holography without limitations on magnification. An electron biprism is strategically mounted between a system of intermediate lenses and projector lenses. The objective lens and the intermediate lenses create a crossover at a specific position, while simultaneously focusing a magnified image at a designated location between the biprism and projector lenses. The system of intermediate lenses consists of three or more stages, enhancing the precision of the imaging process.

Another notable patent is the Fabrication Method of Silicon Nanocrystals. In this process, silicon nanocrystals are formed by irradiating silicon oxide substrates with electron beams at temperatures of 400°C or higher. This method triggers an electron-stimulated decomposition reaction, resulting in the creation of single crystalline silicon nanostructures on the silicon oxide substrate with excellent size and positional controllability.
