1. Application of the Keldysh Formalism to Quantum Device Modeling and Analysis

   0.0 out of 5 stars 

   Papers | 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...

2. Electron-Phonon and Electron-Electron Interactions in Quantum Transport

   0.0 out of 5 stars 

   Papers | 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,...

3. Quantum Ballistic Transport in Semiconductor Heterostructures

   3.0 out of 5 stars 

   Papers | 27 Aug 2007 | Contributor(s):: Michael McLennan

   The development of epitaxial growth techniques has sparked a growing interest in an entirely quantum mechanical description of carrier transport. Fabrication methods, such as molecular beam epitaxy (MBE), allow for growth of ultra-thin layers of differing material compositions. Structures can be...
