14 Jul 2021   Contributor(s):: Neophytos Neophytou, Patrizio Graziosi, Vassilios Vargiamidis
In this work, we describe a computational framework to compute the electronic and thermoelectric transport in materials with multiband electronic structures of an arbitrary shape by coupling density function theory (DFT) bandstructures to the Boltzmann Transport Equation (BTE).

Low Temperature Enhancement of the Thermoelectric Seebeck Coefficient in Semiconductor Nanoribbons
09 Nov 2016   Contributor(s):: Kommini Adithya, Zlatan Aksamija
IWCE 2015 Presentation. We propose a novel approach to achieving a narrow windowshaped TDF through a combination of a steplike 2dimensional densityofstates (DOS) and inelastic optical phonon scattering. A shift in the onset of scattering with respect to the steplike DOS creates a TDF which...

Device Physics Studies of IIIV and Silicon MOSFETS for Digital Logic
25 Jun 2013   Contributor(s):: Himadri Pal
IIIV's are currently gaining a lot of attraction as possible MOSFET channel materials due to their high intrinsic mobility. Several challenges, however, need to be overcome before IIIV's can replace silicon (Si) in extremely scaled devices. The effect of low densityofstates of IIIV materials...

Direct Solution of the Boltzmann Transport Equation in Nanoscale Si Devices
27 Jun 2013   Contributor(s):: Kausar Banoo
Predictive semiconductor device simulation faces a challenge these days. As devices are scaled to nanoscale lengths, the collisiondominated transport equations used in current device simulators can no longer be applied. On the other hand, the use of a better, more accurate Boltzmann Transport...

TwoDimensional Scattering Matrix Simulations of Si MOSFET'S
27 Jun 2013   Contributor(s):: Carl R. Huster
For many years now, solid state device simulators have been based on the driftdiffusion equations. As transistor sizes have been reduced, there has been considerable concern about the predictive capability of these simulators. This concern has lead to the development of a number of simulation...

Lecture 7: The Boltzmann Transport Equation
16 Aug 2011   Contributor(s):: Mark Lundstrom
Semiclassical carrier transport is traditionally described by the Boltzmann Transport Equation (BTE). In this lecture, we present theBTE, show how it is solved, and relate it to the Landauer Approach usedin these lectures

Generalized Monte Carlo Presentation
17 Jun 2011   Contributor(s):: Dragica Vasileska
This presentation goes along with the Bulk Monte Carlo tool on the nanoHUB that calculates transients and steadystate velocityfield characteristics of arbitrary materials such as Si, Ge, GaAs, GaN, SiC, etc. The tool employs a nonparabolic bandstructure.

Solution of the Boltzmann Equation under lowfield conditions
05 Feb 2011   Contributor(s):: Dragica Vasileska
In this presentation it is explained clearly when one can use the relaxation approximation and when one needs to use Rode's iterative method to calculate the lowfield mobility in semiconductors. At the end examples are given of the effective and Hall mobilities which, as can be seen from the...
