PHOTOSENSOR BASED ON GRAPHENE-NANOWIRE HYBRID STRUCTURES AND THE MANUFACTURING METHOD OF THE SAME

摘要

PURPOSE: An optical sensor based on a graphene-nanowire hybrid structure and a manufacturing method thereof are provided to prevent a nanowire from growing on the remaining photoresist of a graphene. CONSTITUTION: A graphene conductor is laminated on the upper side of a substrate. A nanowire collecting unit is formed on the upper side of the graphene conductor. The nanowire is made of CdS, CdSe, or CdTe. The nanowire collecting unit absorbs light energy and generates electron-hole pairs. The metal electrode is connected to both sides of the graphene conductor and transmits photo carriers to the outside.
