Periodic nanopatterning and reduction of graphene oxide by femtosecond laser to construct high-performance micro-supercapacitors

Reduction and patterning of graphene oxide (GO) have been extensively applied in the field of electronic devices such as sensor, transistors and power source. Surface morphology and reduction level of reduced graphene oxide (rGO) directly influence the performance of devices. Herein, we put forward a new method of one-step periodic nanopatterning and reduction of GO using femtosecond laser pulses in air environment. Three-dimensional (3D) laser...
