Importance of the Collisional Broadening of the States across MOSFET Technology Generations

Kannan G., Vasileska D., Arizona State University, US

There are two assumptions made in the derivation of the Fermi’s Golden Rule: (1) it is assumed that the scattering is infrequent which allows us to impose the long time limit and arrive at the [...]

Modeling of Electronic Transport in Molecular Devices

Lamba V.K., Engles D., Malik S.S., Verma M., HCTM Kaithal, IN

Abstract— In this paper a novel approach for simulating electronic transport in nanoscale structures is introduced. We consider an open quantum system (the electrons of structure) accelerated by an external electromotive force and dissipating energy [...]

Quantum transport in nano mosfets

Lamba V.K., Engles D., Malik S.S., Gupta A., HCTM Kaithal, IN

Various quantum mechanical formulations have been used for the modeling of the carrier transport in semiconductor devices. During the 1980s advances in the semiconductor technology made it possible to fabricate conductors so small that the [...]

Implementation of Separable Scattering Mechanisms in Three-Dimensional Quantum Mechanical Simulations of a Silicon Quantum Wire

Gilbert M.J., Akis R., Ferry D.K., Arizona State University, US

In order to understand the operation of any type of semiconductor device, one must consider the effects of scattering. For many years, Monte Carlo has been the workhorse that has yielded great insight into the [...]

Large Scale FDTD Simulation for Microoptics and Metamaterial Investigations – Current Possibilities and Verification Benchmarks

Hieke A., Tramel R., CFD Research Corporation, US

The study of microsystems containing photonic crystals (PC) and meta-materials are rapidly growing fields of research. Finite-Difference Time-Domain (FDTD) full wave electromagnetic solvers are now increasingly used to investigate and design such systems. However, in [...]

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 [...]
