The present work explores the theoretical analysis of copper passivated MgONRs (Cu-MgO-Cu) for possible nanointerconnect applications. The first principles calculations based on density functional theory (DFT) and non-equilibrium Green's function are employed for theoretical investigation. Pristine MgONRs (H-MgO-H) and Cu-MgO-Cu are both thermodynamically stable and are metallic with H-MgO-H being relatively more stable. Further, the I-V characteristics evaluated using the two-probe method reveal the ohmic behavior of Cu-MgO-Cu. The Cu-MgO-Cu device is further investigated for the nanointerconnect applications. The computed nanoscale parasitic components such as quantum resistance (R Q ), quantum capacitance (C Q ), and kinetic inductance (L K ) are computed to be 6.46 kΩ, 5.57 fF/µm, and 58.17 nF/µm, respectively. Furthermore, the delay and power delay product (PDP) of the nanointerconnect are explored which are important attributes of nanointerconnects. The findings suggest the Cu-MgO-Cu nanoribbons with low parasitic parameters can potentially be employed for nanointerconnect applications.

“…Theoretical calculations have indicated the stability of certain adatom-terminated GNR congurations, extending beyond the conventional H-terminated setups, for instance, K, F, O, B, Mg, Ru, and Te, as well as transition-metalterminated GNRs. [31][32][33] These insights illuminate the interplay between chemical modications and the resultant modications in the electronic and geometric characteristics of GNRs, offering a promising avenue for tailoring their properties to specic device applications.…”

“…The surface reveals the abnormal physical and chemical phenomena within the atomic world and navigates future nanotechnology development by changing the electronic behavior within the nanoscale for different material properties. , Even the surface could be measured by tremendous measurement techniques, such as electron microscopy, synchrotron radiation, probe microscopy, and photoelectron spectroscopy; moreover, theoretical calculation results could offer another atomic-scale prospect to increase the knowledge of the surface. The density functional theory (DFT) has valuable accuracy within the atomic scale for solving the issues of the electronic structure of solids. − The atomic-scale bonding variations at the surface might change the band structure behavior by verifying the periodic atom structure, especially the abruptly ended regular structure at the surface, and forming unique material properties compared to bulk materials.…”

The band structure on the surface might be influenced by the abruptly ended periodic structure and change the physical properties of the semiconductor. By using the density functional theory, this research also demonstrates that the Si unit cell has the calculated room-temperature electrical conductivity as 4.01 × 10–6 (Ω–1 cm–1), similar to the experimental result. Thus, the Si(111) plane structures are calculated, and we found out that the one-layer and two-layer plane structures have the theoretical room-temperature electrical conductivities as 129.68 (Ω–1 cm–1) and 547.80 (Ω–1 cm–1), respectively. In addition, the results reveal that the conduction band and valance band of the Si(111) one-layer and two-layer structures will connect on the ⟨111⟩ direction, mainly contributed by Si 3p orbitals. Thus, the band structure at the ⟨111⟩ direction on the Si(111) surface has variation and increases the electrical conductivity to 7 to 8 orders compared to the intrinsic Si and offers new surface science and surface engineering concepts for future applications.
