Application of the Keldysh Formalism to Quantum Device Modeling and Analysis
14 Jan 2008 | | Contributor(s):: Roger Lake
The effect of inelastic scattering on quantum electron transport through layered semi-conductor structures is studied numerically using the approach based on the non-equilibrium Green's function formalism of Keldysh, Kadanoff, and Baym. The Markov assumption is not made, and the energy coordinate...

Electron-Phonon and Electron-Electron Interactions in Quantum Transport
14 Jan 2008 | | Contributor(s):: Gerhard Klimeck
The objective of this work is to shed light on electron transport through sub-micron semi-conductor structures, where electronic state quantization, electron-electron interactions and electron-phonon interactions are important. We concentrate here on the most developed vertical quantum device,...

High Precision Quantum Control of Single Donor Spins in Silicon
14 Jan 2008 | | Contributor(s):: Rajib Rahman, marta prada, Gerhard Klimeck, Lloyd Hollenberg
The Stark shift of the hyperfine coupling constant is investigated for a P donor in Si far below the ionization regime in the presence of interfaces using tight-binding and band minima basis approaches and compared to the recent precision measurements. In contrast with previous effective...

Valley splitting in strained silicon quantum wells modeled with 2 degree miscuts, step disorder, and alloy disorder
14 Jan 2008 | | Contributor(s):: Neerav Kharche, marta prada, Timothy Boykin, Gerhard Klimeck
Valley splitting (VS) in strained SiGe/Si/SiGe quantum wells grown on (001) and 2° miscut substrates is computed in a magnetic field. Calculations of flat structures significantly overestimate, while calculations of perfectly ordered structures underestimate experimentally observed VS. Step...

Atomistic Electronic Structure Calculations of Unstrained Alloyed Systems Consisting of a Million Atoms
14 Jan 2008 | | Contributor(s):: Gerhard Klimeck, Timothy Boykin
The broadening of the conduction and valence band edges due to compositional disorder in alloyed materials of finite extent is studied using an s p3 s ∗ tight binding model. Two sources of broadening due to configuration and concentration disorder are identified. The concentrational disorder...

New Dimension in Performance: Harnessing 3D Integration Technology
29 Nov 2007 | | Contributor(s):: Kerry Bernstein
Despite generation on generation of scaling, computer chips have remained essentially 2-dimensional. Improvements in on-chip wire delay, and in the total number of inputs and outputs has not been able to keep up with improvements to the transistor, and its getting harder and harder to hide it! 3D...

On the Rise of an Electronic Species: Thoughts on the Impending Singularity
29 Nov 2007 | | Contributor(s):: Kerry Bernstein
The human brain is vastly more complex that our best supercomputers; yet it can be argued that both systems evolve towards common underlying solutions to fundamental compute problems. Biologically-inspired electronic technologies already are enabling new products, and inversely, nano-electronics...
