One of the applications is to use a gate to tune the electron-phonon coupling in order to control the carrier density precisely. Recently, researchers at the Technical University of Denmark published an article in Physical Review Letters 118, 046601 (2017) that describes a new flexural-phonon scattering mechanism induced by the electrostatic gating of a graphene device .READ MORE

Today’s chemists, physicists, material scientists, and engineers embrace the use of graphical user interfaces (GUI) in their everyday research and design workflow.
Virtual NanoLab (VNL) works as a GUI for Atomistix ToolKit (ATK), QuantumEspresso, VASP, FHI-Aims, GPAW, LAMMPS, and various other atomic scale simulations codes. VNL, used by over 3500 scientists across the world, is free for academic users. We want to encourage professors to use VNL in their courses, and help students on their journey to understanding the quantum world.

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.
Despite these unfortunate mistakes we appreciate all completed forms, which we can use to improve the quality and user experience of our products. If you have additional questions about the survey, please contact .READ MORE
