Computational Challenges in Nanoscale Device Modeling

Polizzi E., Sameh A., Sun H., Purdue University, US

The development of new simulation tools is critical for the exploration of quantum transport in nanoscale devices. Such simulation is commonly performed by solving self-consistently the transport problem using The Non-Equilibrium Green's Functions (NEGF) formalism [...]

Effects of Structural Deformation and Tube Chirality on Electronic Conductance of Carbon Nanotubes

Svizhenko A., Maiti A., Anantram M.P., NASA Ames Research Center, US

A combination of large scale classical force-field (UFF), density functional theory (DFT) and tight-binding Green’s function transport calculations is used to study the electronic properties of carbon nanotubes under the twist, bending and AFM-tip deformation. [...]

Characterization of “Multipath Interconnects” for Microelectronic and Nanotechnology Circuits

Goel A.K., Eady N.R., Michigan Technological University, US

A multipath interconnect carries a signal by using the concept of parallel processing by providing two or more paths between the driver and the load. These paths are stacked vertically isolated from one another by [...]

Analytic 3D Greens Function Approach to Scattering and Diffraction from Patterned and/or Imperfect Multilayers

Gallatin G.M., Bell Labs, Lucent Technologies, US

The 3D electromagnetic Greens function Gij(x,x) for planar multilayers is constructed from the eigenmodes of Maxwellís equations in the multilayer structure. Other approaches hav been used to derive the Greens function and the derivation here [...]
