Tools

StrainBands powered by: Electronic structure calculations performed by [PWscf and Quantum-Espresso v3.2.2]. Maximally-localized Wannier functions calculated by [Wannier90 v1.0.2].

:This tool can be used to explore the influence of strain on first-principles bandstructures of semiconductors.

DFT calculations with Quantum ESPRESSO

:This tool enables nanoHUB users to run quantum ESPRESSO, a powerful electronic structure code. Users can perform total energy calculations, energy minimization to predict structures, obtain the Kohn-Sham band structure of periodic systems as well as phonons.

ABINIT benzene_wavefunction-tn.gif

:ABINIT is a package whose main program allows to find the total energy, charge density and electronic structure of systems made of electrons and nuclei (molecules and periodic solids) within Density Functional Theory, using pseudopotentials and a planewave basis. ABINIT also includes options to optimize the geometry according to the DFT forces and stresses, or to perform molecular dynamics simulation using these forces, or to generate dynamical matrices, Born effective charges, and dielectric tensors. In addition to the main ABINIT code, different utility programs are provided.

QC-Lab powered by GAMESS qclab_tn.gif

:QC-Lab – Quantum Chemistry Lab. It provides Ab Initio and DFT molecular and electronic structure calculations of small molecules.

nanoMATERIALS SeqQuest DFT powered by SeqQuest

:This tool provides access to the density functional theory code SeqQuest via nanoHUB.org. SeqQuest is being developed at Sandia National Laboratories by Dr. Peter A. Schultz of the Multiscale Dynamic Materials Modeling Department and collaborators. Using SeqQuest the tool enables users to calculate the total energy, atomic forces and stress for molecules, wires, slabs and bulk systems.

nano-Materials Simulation Toolkit powered by Strachan Group MD

:The nanoMATERIALS simulation toolkit enables users to perform molecular dynamics simulations of materials using a variety of force fields as well as electronic structure calculations.
