Stability Analysis in Graphene Nanoribbon Interconnects

Stability analysis in multiwall carbon nanotube bundle interconnects

“…As seen in Fig. 3a, as l increases, the critical point (À1, 0) moves towards outside, similar to that for SWCNT and MLGNR interconnects [31][32][33][34]. In fact, by increasing the bundle length Nyquist diagrams become farther from the critical point (À1, 0) in real positive direction, and according to the fundamental control concepts the system becomes more stable.…”

“…This with the inclusion of the load and the deriver capacitance becomes equivalent to using a 14-pole transfer function. In other words, our approximation is equivalent to a transfer function with 14th-order Padé's approximation, providing much more accurate and realistic numerical results than those that could be obtained by similar analyses presented in [31] with order of four, in [32] with the order of six both for SWCNT-bundle interconnects, and in [33] with the order of four for multi-layer graphene nanoribbon (MLGNR) interconnects. Furthermore, simulations show that for the bundles with 3 6 t 6 7, 3 nm < D 1 < 15 nm, and l = 30 lm, when the number of distributed blocks are varied from N B = 1 to N B = 2, from 2 to 3, from 5 to 6, and from 6 to 7, the relative variation in values of the calculated delays are $65%, 25%, <3.8%, and <3.6%, respectively.…”

“…Kim et al [22] and Zeng et al [23] discussed about the optical stability of CNTs, Chaudhari et al [24], Shin et al [25], and Hasche et al [26] reported on chemical stability of CNTs, Sun et al [27], Lopez [28], Xu et al [29], and Kim et al [30] discussed about the mechanical and thermal stability of CNTs, and Fathi et al [31,32] and Nasiri et al [33,34] focused on the Nyquist stability of CNTs and GNRs Interconnects, respectively.…”

Crosstalk bandwidth and stability analysis in graphene nanoribbon interconnects

“…In the past several years, graphene has attracted much attention due to its superior properties, such as extreme high current carrying capability [2,4,5], long mean free path (i.e., $1 lm at room temperature [3,4]), ballistic transport [6,7], high intrinsic mobility [7][8][9], high thermal/electrical conductivity [9], and straightforward fabrication processes [2,6,10]. The monolayer GNRs electrical intrinsic resistance is too large to be applicable.…”

“…A number of studies on GNR-based interconnects for, signal transmission, relative stability, low swing signaling, and time domain analysis have been found in [6,11,25,26]. The works in [27][28][29][30] have inquired the performance evaluation of CNTs based interconnects.…”
