Bandstructure in Nanoelectronics
01 Nov 2005   Contributor(s):: Gerhard Klimeck
This presentation will highlight, for nanoelectronic device examples, how the effective mass approximation breaks down and why the quantum mechanical nature of the atomically resolved material needs to be included in the device modeling. Atomistic bandstructure effects in resonant tunneling...

On the Reliability of MicroElectronic Devices: An Introductory Lecture on Negative Bias Temperature Instability
28 Sep 2005   Contributor(s):: Muhammad A. Alam
In 1930s Bell Labs scientists chose to focus on Siand Ge, rather than better known semiconductors like Ag2S and Cu2S, mostly because of their reliable performance. Their choice was rewarded with the invention of bipolar transistors several years later. In 1960s, scientists at Fairchild worked...

Modeling and Simulation of SubMicron Thermal Transport
26 Sep 2005   Contributor(s):: Jayathi Murthy
In recent years, there has been increasing interest in understanding thermal phenomena at the submicron scale. Applications include the thermal performance of microelectronic devices, thermoelectric energy conversion, ultrafast laser machining and many others. It is now accepted that...

Parallel Computing for Realistic Nanoelectronic Simulations
12 Sep 2005   Contributor(s):: Gerhard Klimeck
Typical modeling and simulation efforts directed towards the understanding of electron transport at the nanometer scale utilize single workstations as computational engines. Growing understanding of the involved physics and the need to model realistically extended devices increases the...

Multiscale Modeling of the Mechanical Behavior of PolymerBased Nanocomposites
25 Mar 2004   Contributor(s)::
Polymers filled with nanoscale fillers (carbon nanotubes or nanoparticles) exhibit enhanced properties compared with the neat polymer and with the polymer filled with micronsized fillers at same volume fraction. Most interestingly, combinations of exceptional properties may be obtained as, for...

Quantum Electromechanical Systems: Are we there yet?
05 Feb 2004   Contributor(s):: Andrew Cleland
Electrons moving in a conductor can transfer momentum to the lattice via collisions with impurities and boundaries, giving rise to a fluctuating mechanical stress tensor. Driving electrons out of equilibrium by applying the voltage across the conductor, one may control this electromechanical noise.
