Modeling Quantum Transport in Nanoscale Transistors
Papers | 27 Jun 2013 | Contributor(s):: Ramesh Venugopal
As critical transistor dimensions scale below the 100 nm (nanoscale) regime, quantum mechanical effects begin to manifest themselves and affect important device performance metrics. Therefore, simulation tools which can be applied to design nanoscale transistors in the future, require new theory...

Nanoelectronic Modeling Lecture 23: NEMO1D - Importance of New Boundary Conditions
Online Presentations | 02 Mar 2010 | Contributor(s):: Gerhard Klimeck
One of the key insights gained during the NEMO1D project was the development of new boundary conditions that enabled the modeling of realistically extended Resonant Tunneling Diodes (RTDs). The new boundary conditions are based on the partitioning of the device into emitter and collector...

Nanoelectronic Modeling Lecture 24: NEMO1D - Incoherent Scattering
Online Presentations | 02 Mar 2010 | Contributor(s):: Gerhard Klimeck
Incoherent processes due to phonons, interface roughness and disorder had been suspected to be the primary source of the valley current of resonant tunneling diodes (RTDs) at the beginning of the NEMO1D project in 1994. The modeling tool NEMO was created at Texas Instruments to fundamentally...

Notes on Scattering and Mobility in 1D, 2D, and 3D
Teaching Materials | 03 Nov 2009 | Contributor(s):: Dmitri Nikonov, Md. Sayed Hasan, George Bourianoff
Derivation of the phonon-limited mobility is reviewed for electrons in bulk (3D) orquantum confined (2D and 1D) semiconductor structures. Analytical estimates are madethat show the mobility in quantum confined structures is, in general, lower or no higherthan in non-confined ones.

Two-Dimensional Scattering Matrix Simulations of Si MOSFET'S
Papers | 27 Jun 2013 | Contributor(s):: Carl R. Huster
For many years now, solid state device simulators have been based on the drift-diffusion 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...
