Latest Patents

One of Daesu Lee's latest patents is titled "Vanadium dioxide heterostructures having an isostructural metal-insulator transition." This patent describes heterostructures that include a bilayer composed of epitaxial layers of vanadium dioxide with varying rutile-to-monoclinic phase transition temperatures. The invention provides electrical switches that incorporate these heterostructures, which undergo a single-step, collective, metal-insulator transition at an electronic transition temperature. Below this temperature, the layer with the higher rutile-to-monoclinic phase transition temperature remains in an insulating monoclinic crystalline phase, transitioning to a metallic monoclinic crystalline phase above the electronic transition temperature.

Another notable patent is "Vanadium dioxide-based optical and radiofrequency switches." This patent presents switches designed for electromagnetic radiation, including radiofrequency and optical switches. The switches utilize layers of high-quality vanadium dioxide composed of interconnected crystalline domains that share the same crystal structure and orientation. These innovations have the potential to enhance the performance of various electronic and optical devices.
