The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

we present a direct-write, relatively low-cost and robust approach for fabricating sub-10 nm GNR-based FETs using electrochemical atomic force microscopy lithography with an alternating current (AC) bias, obviating the need for electrodes.

C2weakest assumption

The assumption that the electrochemical process with AC bias can reliably produce functional sub-10 nm GNR FETs with the claimed low defect density and high resolution without the need for electrodes, as no specific performance data is detailed in the abstract.

C3one line summary

Direct electrochemical AFM lithography fabricates sub-10 nm GNR FETs electrode-free with high resolution and low defects.
