Join us for a free webinar on how to include electron-phonon scattering effects in large scale atomistic device simulations using the Special Thermal Displacement (STD)-Landauer method in VNL-ATK 2017. These effects play a central role in the performance of nano-scale electronic devices, such as rectifiers and transistors.
Time: The webinar will be held on December, 14th, 9 am and 8 PM CET (Central European Time, Denmark). The duration is about 30 minutes.
Presented by: Daniele Stradi, PhD and Ulrik Grønbjerg Vej-Hansen, PhD from Synopsys QuantumWise.
You can register here.
This webinar is targeted to:
- ATK users who already perform atomistic device simulations;
- egineers/researchers who perform TCAD simulations of devices.
We will cover:
- why electron-phonon scattering effects play a central role in the performance of nano-scale electronic devices;
- how and why the STD-Landauer method works (as an approximation for the current including explicit electron-phonon couplings) for including electron-phonon scattering effects and why it is so efficient;
- how to set up, run STD-Landauer calculations and analyze results, following a case study on a Si p-n junction;
- example applications of the STD-Landauer method for calculating electrical characteristics of semiconductor devices.
Afterwards, there will be time for questions and discussion.
After registerimg, you will receive a confirmation email containing information about joining the webinar. For any questions about the webinar, please contact .
We look forward to meeting you during the webinar!

Synopsys QuantumWise and a group of researchers at the Technical University of Denmark present a new large scale at low cost “Special Thermal Displacement (STD)-Landauer” method  for treating electron-phonon coupling (EPC) effects. EPC, such as Phonon-assisted tunneling, plays a central role in the performance of ultra-scaled electronic devices and is one of the major challenges from the viewpoint of both experiments and simulations. The method is conceptually simple (see the concept below) and much more efficient than any existing first-principles transport methods including EPC for enabling first-principles modeling of realistic rectifiers and transistors.READ MORE

Previous research have posited that amorphous Selenium has a chain-like structure, independent of the manufacturing processes. However, a recent study in a collaboration between experimental teams from Stony Brook University and Oak Ridge National Laboratory found that the structure of amorphous Selenium (a-Se) films manufactured by vapor deposition (VD) and melt-quenched (MQ) processes are predominantly composed of ring-like and chain-like molecules, respectively. Given that no experimental technique is able to query the detailed three-dimensional atomic arrangements in glassy semiconductors, scientists are hoping that simulations can offer more evidence and structural detail.READ MORE

A survey was sent out over the weekend to a large number of ATK and Virtual NanoLab users, mainly to persons who requested a trial license.
We hereby confirm that the email is not spam, and it is correct that you can obtain an extended trial license by completing the survey.
The survey was formulated by a small group of master students from Judge Business School in Cambridge, UK, who work as consultants for QuantumWise. Unfortunately, they didn't double-check the content of the email and survey with us before sending it out, resulting in a misspelling of Virtual NanoLab throughout the email and survey, and other minor mistakes.
