Abstract: Disclosed is a graphene-based ternary barristor using a Schottky junction graphene semiconductor. A graphene channel layer is doped with N-type and N-type dopants to have two different Fermi levels and form a PN junction. Accordingly, a voltage is applied to a gate electrode layer to move the Fermi levels of the graphene channel layer and adjust the height of the Schottky barrier, thus generating current. Also, the height of the Schottky barrier is adjusted depending on the doping concentration of the graphene channel That is, the height of the Schottky barrier is changed depending on the applied gate voltage, and thus the flow of current is changed. Also, it is possible to adjust the height of the Schottky barrier by adjusting the doping concentration of the graphene channel. Accordingly, since the graphene-based ternary barristor has a high current ratio by adjusting a gate voltage, the graphene-based ternary barristor may be applied to a logic circuit.

Abstract: Vertical high power LEDs are the technological choice for the application of general lighting due to their advantages of high efficiency and capability of handling high power. However, the technologies of vertical LED fabrication reported so far involve the wafer-level metal substrate substitution which may cause large stress due to the mismatch between metal substrate and LED layer. Moreover, the metal substrate has to be diced to separate LED dies which may cause metal contamination and thus increase the leakage current. These factors will lower the yield of LED production and increase the cost as well. The present invention is to disclose a novel method for the fabrication of GaN vertical high power LEDs and/or a novel method for the fabrication of GaN vertical high power LEDs which is compatible to mass production conditions. The novelty of the invention is that the island metal plating is conducted with the help of pattern formation techniques.
