Abstract:
PURPOSE: A nano power generation element and a method for manufacturing thereof are provided to independently and consistently operate by using piezoelectric characteristics of a hexagonal boron nitride atomic layer. CONSTITUTION: A hexagonal boron nitride atomic layer(120) is formed on a base substrate(110). The hexagonal boron nitride atomic layer has a single layer structure combined with a nitrogen atom and a boron atom in a hexagon. The hexagonal boron nitride atomic layer has piezoelectric characteristics to convert from the physical energy to the electrical energy. A first electrode(130) is formed on the hexagonal boron nitride atomic layer. A second electrode(140) is separately formed with the first electrode.

PURPOSE: A piezoelectric energy harvestor by a passivation effect is provided to increase power by depositing an organic/inorganic n-type material in an inorganic material p- type semiconductor piezoelectric material and to secure the self operation of a device. CONSTITUTION: A lower electrode, a piezoelectric material layer, a second material layer, and an upper electrode are successively formed on a substrate. The piezoelectric material layer is made of an n-type material. A first material layer is made of a p-type material. The second material layer is made of the mixture of the n-type material and the p-type material. The upper electrode and the lower electrode are formed to induce electric energy.
