Reproducing DFT calculations of Al2O3/GaAs interface structure and Fermi level pinning
20 Oct 2014 | | Contributor(s):: Alejandro Strachan
The goal of this resource is to demonstrate how to reproduce the results of the following research paper using the nanoMATERIALS SeqQuest DFT simulation tool on nanoHUB. In addition to reproducing the paper's results, users can run variations of the simulation to explore the...
OnlineSimulation tutorial and assignment: bonding curves in H2 and He2 molecules
18 Feb 2015 | | Contributor(s):: Alejandro Strachan
In this tutorial students will use density functional theory (DFT) calculations using the nanoHUB tool SeqQuest to study bonding in two simple molecules: H2 and He2. The tutorial shows how to compute energy as a function of bond distance and extract the equilibrium bond distance and bond...
OnlineSimulation tutorial and assignment: electronic structure and spin in O2 molecule
In this tutorial students will use density functional theory (DFT) calculations using the nanoHUB tool SeqQuest to study the electronic structure and bonding in the O2 molecular. The tutorial shows how to predict the relaxed bond distance in O2 (i.e. minimum energy structure) both for...
OnlineSimulation tutorial and assignment: electronic structure and spin of the O atom
In this tutorial students will use density functional theory (DFT) calculations using the nanoHUB tool SeqQuest to study the electronic structure of the oxygen atom. The tutorial shows how to compute energy for the spin 1 (triplet) and spin 0 (singlet) states and analyze the exchange...

Computational Investigation of Point Defect Formation and Migration in Nuclear Fuels
09 Feb 2012 | | Contributor(s):: Susan Sinnott
The stabilities of selected fission products are investigated as a function of stoichiometry in uranium oxide. The approach is density functional theory (DFT) that is used to calculate the incorporation and solution energies of solid and gaseous fission products at the anion and cation vacancy...
Density Functional Theory: A great physics success story
23 Feb 2012 | | Contributor(s):: Kieron Burke
Density functional theory began with the work of Thomas and Fermi, at about the same time as Schroedinger wrote his famous equation. I will explain in general terms what density functional theory is and describe some problems of current interest.
