Efficient and realistic device modeling from atomic detail to the nanoscale

As semiconductor devices scale to new dimensions, the materials and designs become more dependent on atomic details. NEMO5 is a nanoelectronics modeling package designed for comprehending the critical multi-scale, multi-physics phenomena through efficient computational approaches and quantitatively modeling new generations of nanoelectronic devices as well as predicting novel device architectures and phenomena. This article seeks to provide updates on the current status of the tool and new functionality, including advances in quantum transport simulations and with materials such as metals, topological insulators, and piezoelectrics.

Archimedes, the free Monte Carlo simulator: A GNU package for submicron semiconductor devices on nanoHUB

Archimedes is the GNU package for Monte Carlo (MC) semiconductor devices simulations. Since its very first release in 2005, users have been able to download the source code under the GNU Public License (GPL). Since then, many features have been introduced in this package, including the ability to perform Archimedes simulation on nanoHUB.org. This paper presents the current code status and anticipated developments.

Quantum dot lab: an online platform for quantum dot simulations

An online platform for simulating quantum dots has been shown. The tool has been deployed on nanoHUB and can simulate quantum dots with varying degrees of complexity acting as a research and learning tool for the scientific community. The tool will include ability to simulate random alloys and ability to import disordered structures and calculate energy levels for such disordered systems in the future.
