“…Kinetic/magnetic inductances (L K /L M ), and quantum/electrostatic capacitance (C E /C Q ), as seen in the image, all have a substantial effect on interconnect performance. The C Q and L K appear due to the exchange correlational effects and are unique to the nanoscale devices [13]. Furthermore, the resistance in the two probe setup can be evaluated as follows [7]…”

“…There are significant issues with using Cu as a metal connection at lower dimensions due to its increased resistivity, grain boundary scattering, and electron migration [8], [9]. Various 2D materials have been reported for use in the design of metal interconnects at the nanoscale [10]- [13]. Theoretical research has shown that GNRs can be used for nanoscale interconnects with chemical edge modification [14] or by doping [15].…”

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.

“…In the semiconductor industry, interconnects are the important interest for Giga scale and Tera scale integrations, due to the challenges of delay, power dissipation, noise and jitter they induce on one another, and their vulnerability to electromigration (EM) [1][2][3][4]. To overcome these challenges, one-dimensional nanomaterials such as carbon nanotubes (CNTs), nanowires, nanoribbons, etc [5][6][7][8][9] have been explored and reported by a number of researchers. Of these, the one-dimensional form of graphene and metallic graphene nanoribbons (GNRs) are good candidates for interconnects.…”

To analyse the suitability of zigzag graphene nanoribbons (ZGNRs) as interconnects, the influence of halogen (F, Cl, Br, and I) passivation on ZGNRs has been analysed in terms of structural stability, electron transport, and thermal conductivity, as well as the performance parameters of the interconnects. The computation is performed using first-principle density functional theory with a non-equilibrium Green’s function approach, while the performance parameters of the interconnects such as delay and power delay product are computed using a HSPICE simulator tool. The formation energy analysis confirms the stability trend for halogen-passivated ZGNRs as F > Cl > Br > I. With moderate stability, the I- and Br-passivated ZGNRs have relatively better current–voltage characteristics in comparison to F and Cl. However, the Cl-passivated ZGNRs have relatively better interconnect parameters in comparison to other proposed halogenated systems (one edge and both edges), measured in terms of kinetic inductance and quantum capacitance. Another requirement of any good interconnect is less delay and less average power, which have also been computed and found to be relatively better in the case of Cl-passivated ZGNRs. Thus, among the halogen-passivated GNRs tested, those that are Cl-passivated defend their selection for interconnect applications well.
