文摘
- •
Multi-bandgap photodetectors with an inherently lattice-matched structure by the natural stacking of graphene oxide nanoribbons is demonstrated.
- •
TEM images reveal a multilayer graphene oxide nanoribbon with gradually increasing widths.
- •
Photoelectrical measurements show visible-light spectrum absorption, which indicates that the various energy bandgaps of the multi-layer GONRs.
