  • Simulating the chemical bonding of GNRs to substrates at the basal edge.
  • Analyzing the electronic and magnetic properties of both free-standing and substrate-supported GNRs.

    • Main Results:

    • Demonstrated the feasibility and mechanical robustness of synthesizing both nickel (Ni)- and diamond-supported upright GNRs.
    • Showcased that substrate-supported upright GNRs retain electronic and magnetic properties comparable to free-standing GNRs.
    • Calculated that upright GNRs offer an extremely small footprint, ideal for miniaturization.

    Conclusions:

    • Upright GNRs on substrates are a viable and robust configuration for advanced electronic applications.
    • The unique properties of substrate-supported GNRs pave the way for subnanometer spintronic devices.
    • Theoretically achievable field-effect transistor (FET) densities of up to 10(13) per cm(2) highlight the potential for ultra-high-density microchips.
