Tailoring Molecular Devices for its Electronic Properties

Lamba V., Engles D., Pati S.K., Haryana College of Technology & Management, Kaithal, IN
In present work we studied Conduction properties of nanoscale contacts DFT/NEGF approach. Such calculations give insight into details behind the conductance that is not readily available in experiments. For example, we may learn how the [...]

First-principles Modeling of Magnetic Memory Components — Preliminary Results on the Effects of Interface Oxides

Stilling M., Stokbro K., Flensberg K., Atomistix, DK
Magnetotunnel junctions (MTJs), exhibiting high tunneling magnetoresistance (TMR), are currently being employed in new generations of hard disk drive (HDD) read heads and novel magnetic random access memory (MRAM) technology. We have modeled such spintronic [...]

First-principles Study of Electron Transport through Atomistic Metal-Oxide-Semiconductor Structures

Zhang X., Fonseca L.R.C., Demkov A.A., Motorola, Inc., US
We describe a theoretical scheme to combine first-principles molecular dynamics simulation and non-perturbative scattering theory for transport calculations. We compare our approach with published results for electron transport through a single Al atom. The method [...]

Molecular Control of the Drain Current in a Buried Channel MOSFET

Yang J., de la Garza L., Thornton T.J., Kozicki M., Gust D., Arizona State University, US
We present results from a buried channel MOSFET with a molecular monolayer deposited on the surface. After attachment of the monolayer, the threshold voltage of the device shifts by approximately – 4.5 V. We explain [...]

Electron Vorticity – Internal Energy Formulation of the Hydrodynamic Model of Electron Transport

Mohseni K., Shakouri A., University of Colorado, US
The hydrodynamic model of electron transport is revisited. By rearranging the governing equations a new set of equations in terms of the electron vorticity and internal energy is derived. The advantage of the new set [...]

Electron Vortices in Semiconductor Devices

Mohseni K., Shakouri A., Ram R.J., California Institute of Technology, US
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 [...]

High-Field and High-Temperature Transport in n-Type 3C-SiC

Zhang Y., Zhang Y., Xidian University, CN
The physical model used in Monte Carlo simulation is developed considering the energy gap structures and the main scattering mechanisms in details. The static electron transport in the material 3C-SiC is analyzed by single particle [...]
