Latest Patents
One of Hae Gwon Lee's latest patents is a short-wavelength optoelectronic device that includes a field emission device. This invention provides a method for fabricating a 200-250 nm short-wavelength optoelectronic device. It combines an optical device with multiple acceleration electrodes and a field emission device, utilizing a semiconductor with a 5-6 eV energy band gap. The principle behind this device is that a highly energetic electron injected from the field emission device produces an electron-hole pair. When the electron recombines with the hole, short-wavelength photons are emitted, which correspond to the energy level of the quantum well. This innovation eliminates the need for dopants in forming n-p junctions in the semiconductor, achieving high energy efficiency due to the generation of one or more electron-hole pairs from highly energetic electrons.
Another notable patent is the effusion cell assembly for epitaxial apparatus. This assembly includes an effusion cell containing a growing material and a heater that supplies heat to the effusion cell to facilitate the effusion of the growing material. The design features a supporting plate, a bolt, a cell flange, and bellows that allow for the separation of the cell assembly from a vacuum chamber while maintaining the vacuum in the chamber. This invention enhances the functionality of epitaxial apparatus by ensuring efficient vacuum management.
