Liquid‐Processed 2D Aromatic Amorphous Carbon: Defect Engineering and Universal Transport Scaling
Researchers have introduced a deterministic method to convert liquid‑processed graphene oxide into a quasi‑amorphous 2D carbon, termed quenched reduced graphene oxide (qRGO), by applying rapid thermal quenching.

Electrical measurements reveal that qRGO transitions to a strongly disordered regime governed by variable‑range hopping, yet both qRGO and RGO obey a universal power‑law resistivity scaling. This approach offers a scalable route to functional amorphous carbon films with tunable electronic properties.
