2D nanocomposite photoconductive sensors fully dry drawn on regular paper

摘要

We proposed a new type of low-cost and environmentally friendly photoconductive sensor, based on GaSe/graphite nanocomposite fully dry drawn on paper. The proposed fully-drawn nanocomposite sensors successfully utilize the unique combination of structural and electrical properties of a layered semiconductor and graphite. In spite of the relatively pure photosensitivity of the proposed photodetectors, we believe that this work is the first step for the further development and enhancement of extremely simple and low-cost paper-based dry drawn layered semiconductor/ graphite nanocomposite sensors.
