Modeling Artificial Molecules Composed of Coupled Quantum Dots
Recently, there has been much interest in coupled quantum dots. With individual dots, if the energy levels can be resolved, then one can think of a dot as representing an "artificial atom" [1]. Thus, fabricating [...]
Self-Consistent Calculations of Spatial Electron Densities in Quantum Dots Using a Coupled Recursive Green’s Function and Poisson Solver
We are utilizing the Recursive Green's function method to calculate the conductance in quantum dots as a function of Fermi energy, magnetic field and random potentials. We have extended the use of the method to [...]
Ensemble Monte Carlo Simulation of Raman Scattering in an AlxGa1-xAs System to Determine the Relative Strength of the Polar Optical Modes
A Monte Carlo simulation is used to study Raman scattering and the relative strengths of the polar optical modes in an AlxGa1-xAs system. The dual polar optical modes in the system are incorporated by including [...]
Electron Vortices in Semiconductor Devices
The hydrodynamic model of electron transport in semiconductors is analyzed and in analogy to uid mechanics the transport equation for the electron vorticity, rv, is derived. Aside from the classical hydrodynamic sources of vorticity, collision [...]
Hybrid CA/Monte Carlo Modeling of Charge Transport in Semiconductors
We report on the modeling of ultra-small MOS devices using a newly developed full band device simulator. The simulation tool is based on a novel approach, featuring a hybrid Monte-Carlo/Cellular Automata simulation engine self-consistently coupled [...]
Long-Range Coulomb Interactions in Small Silicon Devices: Transconductance and Mobility Degradation
In small silicon devices,conduction electrons in the channel are subject to long-range Coulomb interactions with electrons in the heavily-doped drain,source,and gate regions.We show that for devices with channel lengths shorter than about 40 nm and [...]
