  • Tuning method for active metamaterials using IGZO Schottky diodes
    Patent number: 12237427
    Abstract: A tuning method for active metamaterials using IGZO Schottky diodes, wherein the IGZO Schottky diode comprises a substrate, a Schottky electrode, amorphous IGZO active layer, and an ohmic electrode from the bottom up. The method comprises steps as follows: (1) Metamaterials are used as the Schottky electrodes, and amorphous IGZO active layers are used to fully cover the capacitive gap structures in the metamaterials; such capacitive structures in the metamaterials are bonded to the amorphous IGZO active layers to form Shottky barriers; (2) The resulting IGZO Schottky diodes from step (1) are used to tune the metamaterials dynamically.
