News and Announcements / New QuantumATK O-2018.06 Release: Webinar Recording and Slides

« on: June 28, 2018, 11:42 »

Check out the  recording and slides of our webinar highlighting the new features and functionalities of the newly released QuantumATK O-2018.06 software package for atomic-scale modeling (the full release letter can be found here).

Notice that VNL/ATK has a new name - QuantumATK. QuantumATK includes quantum mechanical methods such as DFT and semi-empirical models and the following modules: NEGF (Non-equilibrium Green's Function), ForceField, and our advance graphical user interface  NanoLab (former VNL). We are very excited as it is the first major release since we became part of Synopsys in Sep, 2017.

Presented by: Anders Blom, PhD and Umberto Martinez Pozzoni, PhD, specialists in atomic-scale simulations at Synopsys.



During this webinar, discover the following new features and functionalities of QuantumATK O-2018.06:

• Plane-Wave simulation engine including hybrid functional HSE06
• New pseudopotentials
• Performance improvements for periodic and device (with Non-Equilibrium Green’s Function method) density functional theory (DFT) simulations
  Introduction to the advanced StudyObject framework to perform complex tasks such as:

                -Device geometry optimizations
                -IV characteristics enabling systematic variation of both, the gate-source and the drain-source voltages of a device
                -Simulating neutral and charged point defects in bulk materials and interfaces: defect  formation energies and transition levels

• Special Quasi-random Structure (SQS) generator for simulating alloys
• New Builder features for building and handling your structures
• And more new exciting features!

Greetings,
Synopsys QuantumATK Team

News and Announcements / Join us for a free webinar on 27Feb on how to simulate interfaces in electronics

« on: January 31, 2018, 11:02 »

Join us for a free webinar featuring a demonstration of simulating interfaces at the atomic scale using QuantumATK (former VNL-ATK).

You can register here.

Interfaces, such as metal-semiconductor, are becoming increasingly more important due to continued down-scaling of electronic devices. For example, the detailed understanding of the metal-semiconductor contact resistance at the atomic scale is necessary in order to tailor the contact resistance of the devices. You can learn more about simulating interfaces with QuantumATK in the  TCAD News, December 2017.

This webinar might also be interesting to researchers/engineers in other application areas than electronics, as simulating interfaces is important when modeling batteries, solar cells and materials in general.

Time:
The webinar will be held twice on February, 27th:
9 am CET (CET - Central European Time, Denmark)
6 pm CET (good time for participants from Americas).

The duration is 1 hour (including 15 min Q&A session).

Presented by: Daniele Stradi, PhD and Petr Khomyakov, PhD - Senior Application Engineers from Synopsys QuantumWise.



Discover the simulation of interfaces with QuantumATK:
- Learn about our state-of-the-art method for simulating interfaces (Density Functional Theory + Non Equilibrium Green's Function method).
- Create and relax the structure of the interface, dope the semiconductor.
- Calculate electronic structure (band diagram) of the interface and the most important parameters that characterize an interface: Schottky barrier and contact resistance.
- Perform a physically sound analysis, compare with experimental results.
- Learn from the Global Foundries and IBM Research study of the TiGe/Ge interface and the Imec study of the TiSi/Si interface, both carried out using QuantumATK.

Afterwards, there will be time for questions and discussion.

For any questions about the webinar, please contact [email protected]. We look forward to meeting you during the webinar!

News and Announcements / Free-webinar: include electron-phonon scattering effects in device simulations

« on: December 4, 2017, 15:06 »

Synopsys QuantumWise will host a free webinar on how to include electron-phonon scattering effects in large scale atomistic simulations of electronic devices 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.

The webinar will be held TWICE:

1)  December, 14th, 9 - 9.30 AM CET (Central European Time, Denmark)

2) December, 14th,  8 - 8.30 PM CET (Central European Time, Denmark) - good time for participants in Americas

Presented by: Daniele Stradi, PhD and Ulrik Grønbjerg Vej-Hansen, PhD from Synopsys QuantumWise

This webinar is targeted to:

- ATK users who already perform atomistic device simulations;
- engineers/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 the case study on a silicon p-n junction: https://docs.quantumwise.com/casestudies/std_transport/std_transport.html
- example applications of the STD-Landauer method for calculating electrical characteristics of semiconductor devices.

Afterwards, there will be time for questions and discussion.

After registering, you will receive a confirmation email containing information about joining the webinar. For any questions about the webinar, please contact [email protected].
