11 Jun 2009   Contributor(s):: Gerhard Klimeck, Benjamin P Haley
This video shows the simulation and analysis of a several PN junctions using PN Junction Lab, which is powered by PADRE. Several powerful analytic features of this tool are demonstrated.

Is dual gate device structure better from a thermal perspective?
01 Sep 2008   Contributor(s):: Dragica Vasileska, Stephen M. Goodnick
This presentation illustrates several points. First, it is shown that in nanoscale devices there is less degradation due to heating effects due to nonstationary nature of the carrier transport (velocity overshoot) in the device, which, in turn, makes less probable the interaction with phonons....

20 Aug 2008   Contributor(s):: Dragica Vasileska, Gerhard Klimeck
This exercise helps the students learn the importance of the nonparabolic band approximation for large carrier energies.

Uniform versus delta doping in 1D heterostructures: an Exercise
15 Aug 2008   Contributor(s):: Dragica Vasileska, Gerhard Klimeck
This exercise is designed to demonstrate that delta doping leads to larger sheet electron density in the channel and it also allows for better control of the charge density in the channel region of High Electron Mobility Transistors (HEMTs).

Parallel Conduction Channel: an Exercise for 1D Heterostructure Lab
15 Aug 2008   Contributor(s):: Dragica Vasileska, Gerhard Klimeck
This exercise uses the 1D Heterostructure Lab, which demonstrates that adding more dopants in the buffer layer becomes ineffective after certain critical doping density. Beyond this critical doping density, additional dopants practically fill in the parallel conduction channel that sits in the...
