Study On  Self-Folding Mechanism and Photoelectric Property of Three-Dimensional Graphene C Ubic S Tructure

Abstract

In this paper, the self-folding mechanism of 3D graphene cube is investigated. It is indicated that the primary cause of self-folding is the surface tension generated by the hinge structure after melting.  Photoelectric characterization demonstrates that the 3D-graphene exhibits pronounced wavelength-dependent photo response, achieving 26% enhancement in photocurrent density under oblique illumination (θ =90°) , and the 3D-graphene cube produces strong sensitivity to the different angles of the incident light. This work provides insights for the development and application of self-folding graphene and other 3D materials, with high application value in the fields of flexible electronics, supercapacitors and bio-interfaces.
