Carbon Nanotube Based VLSI Interconnects: Analysis and by Brajesh Kumar Kaushik, Manoj Kumar Majumder

By Brajesh Kumar Kaushik, Manoj Kumar Majumder

The short basically makes a speciality of the functionality research of CNT established interconnects in present study situation. diversified CNT constructions are modeled at the foundation of transmission line idea. functionality comparability for various CNT buildings illustrates that CNTs are extra promising than Cu or different fabrics utilized in worldwide VLSI interconnects. The short is prepared into 5 chapters which customarily talk about: (1) an outline of present study situation and fundamentals of interconnects; (2) special crystal constructions and the fundamentals of actual homes of CNTs, and the creation, purification and functions of CNTs; (3) a short technical overview, the geometry and identical RLC parameters for various unmarried and bundled CNT constructions; (4) a comparative research of crosstalk and hold up for various unmarried and bundled CNT buildings; and (5) a number of certain combined CNT package deal constructions and their similar electric models.

If CNT can be considered as an infinitely long cylinder, there are two wave vectors associated with it: (1) the wave vector parallel to CNT axis k|| that is continuous in nature due to the infinitely long length of CNTs and (2) the perpendicular wave vector k⊥ that is along the circumference of CNT. 14) where D represents the diameter of CNT and m is an integer. The quantized v­alues of allowed k⊥ for CNTs are obtained from the boundary condition. 8 a A first Brillouin zone of graphene with conic energy dispersions at six K points.

The model also takes into account various electron–phonon scattering mechanisms including emission and absorption of optical phonons and interaction with acoustic phonons. Recently, Li et al. 2 a Equivalent circuit for a metallic SWNT bundle interconnects, where Na and Nb represent number of SWNTs in ground and upper level, respectively. 2a for SWNT bundle interconnects (2009a) presented the current state of research in carbon based nanomaterials, particularly for one-dimensional (1D) form of CNTs and GNRs.

For large CNT radius, Salahuddin et al. l. parameters. Furthermore, a semiclassical one-dimensional (1D) electron fluid model was presented (Xu and Srivastava 2009) that takes into account electron–electron repulsive force. Based on the 1D electron fluid theory, the authors developed a transmission line model for metallic CNT interconnects by using classical electrodynamics. Recently, Srivastava et al. 2) based on the onedimensional fluid theory. l. scattering resistance, kinetic inductance, and quantum capacitance of each shell, respectively.
