Latest Patents

One of his 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 invention is that an electron-hole pair is produced using a highly energetic electron injected from the field emission device. When the electron recombines with the hole, short-wavelength photons are emitted, which are confined in a quantum well to emit light corresponding 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 for a highly integrated multicolor light-emitting device. This invention addresses the challenge of emitting multiple colors from a single chip by integrating light-emitting devices of different colors. The device comprises a plurality of light-emitting elements formed on a substrate, each consisting of multiple semiconductor layers. Each light-emitting element radiates light of different wavelengths, showcasing Baek's ability to innovate in the realm of multicolor light emission.
