Latest Patents
Among his latest patents, the UV light emitting device stands out for its intricate design. This device comprises an n-type contact layer that includes either an AlGaN layer or an AlInGaN layer, alongside a p-type contact layer made of the same materials. The active layer features a multi-quantum well structure strategically placed between these contact layers. It incorporates barrier layers and well layers, with well layers containing electrons and holes distributed according to probability principles. The barrier layers, made of either AlInGaN or AlGaN with an aluminum content of 10% to 30%, are constructed to prevent the spreading of electrons and holes between adjacent well layers.
In addition, Lee has developed a near UV light emitting device that also showcases his expertise. This device includes an n-type contact layer, a p-type contact layer, and an active area arranged in a multi-quantum well structure. Moreover, it features an electron control layer designed to increase aluminum content compared to the adjacent layers, which impedes electron flow into the active area. This innovative approach enhances recombination rates of electrons and holes within the active area.
