Abstract:
본 발명은 나노와이어를 이용한 발전 장치에 관한 것으로서 N형 반도체인 나노와이어와 P형 반도체로 이루어진 수광부를 포함하고, 나노와이어는 기계적 에너지를 전기적 에너지로 변환시키는 압전효과를 갖는 물질로 이루어져 있고, 수광부에 가해지는 압력이 나노와이어에 전해지도록 수광부에 나노와이어를 접촉시키면서, 수광부와 나노와이어가 접촉한 경우 PN접합을 형성하는 것을 특징으로 하며, 나노와이어와 수광부가 접촉시 PN 접합구조가 형성된 후, 태양광 에너지를 흡수함으로써, 전류를 발생시킴과 동시에 수광부에 전달된 진동 또는 압력이 압전효과를 갖는 나노와이어에 전달됨으로써 전류를 발생시킬 수 있다.
Abstract:
PURPOSE: A forming method of a graphene thin film on an insulator layer, and a graphene thin film thereof are provided to minimize a patterning process of a graphene thin film, and to form a graphene thin film directly on an insulator, thereby omitting a process of moving a graphene to other insulator layer by etching a metal substrate or a metal catalyst layer. CONSTITUTION: A forming method of a graphene thin film on an insulator layer comprises the steps of: forming a photosensitizer on a metal layer in a state an insulator layer is formed on a substrate and a metal layer is formed on the insulator layer (100); forming a photosensitizer pattern by exposing and developing the photosensitizer layer (110); heating the photosensitizer pattern (120); and forming a graphene between the metal layer and the insulator layer by carbon atoms comprising the photosensitizer pattern which is penetrated through the metal layer as a result of the heating in the previous step.

Abstract:
The present invention relates to conductive cotton fiber, a manufacturing method thereof and a solar-cell cotton fiber using the same. More specifically, natural cotton fiber is changed into being conductive by covalent bonds that are generated between the natural cotton fiber and iodine by adding the iodine to the natural cotton fiber. Accordingly, the conductive cotton fiber, the manufacturing method thereof and the solar-cell cotton fiber using the same according to the present invention can absorb or block harmful electromagnetic waves generated from electronic devices.
