چکیده

A structure map for AB2 type monolayers of 3844 compounds is constructed by high-throughput DFT calculations with the symmetry-unconstrained geometry optimizations starting from ferromagnetic 1T, 1H and planar structures as initial states.

The AFLOW standard for high-throughput materials science calculations

The Automatic-Flow (AFLOW) standard for the high-throughput construction of materials science electronic structure databases is described. Electronic structure calculations of solid state materials depend on a large number of parameters which must be understood by researchers, and must be reported by originators to ensure reproducibility and enable collaborative database expansion. We therefore...

Electronic Structure Calculations at Macroscopic Scales using Orbital-free DFT

In this chapter we provide an overview of the recently developed coarse-graining technique for orbital-free density functional theory that enables electronic structure calculations on multi-million atoms. The key ideas involved are: (i) a local real-space formulation of orbital-free density functional theory; (ii) a finite element discretization of the formulation; (iii) a systematic means of a...

High-throughput DFT calculations of formation energy, stability and oxygen vacancy formation energy of ABO3 perovskites

ABO3 perovskites are oxide materials that are used for a variety of applications such as solid oxide fuel cells, piezo-, ferro-electricity and water splitting. Due to their remarkable stability with respect to cation substitution, new compounds for such applications potentially await discovery. In this work, we present an exhaustive dataset of formation energies of 5,329 cubic and distorted per...

Structure calculations of polyethylene crystals: A DFT approach

Density functional theory (DFT) calculations are performed to find the structural parameters of orthorhombic polyethylene crystal. Computations are carried using Plain wave self-consistent field method implemented in the PWscf software and various pseudo-potentials are used. The calculated values of geometrical parameters are in good agreement with reported values, but the cohesive energy show ...

Modelling Catalyst Surfaces Using DFT Cluster Calculations

We review our recent theoretical DFT cluster studies of a variety of industrially relevant catalysts such as TiO(2), gamma-Al(2)O(3), V(2)O(5)-WO(3)-TiO(2) and Ni/Al(2)O(3). Aspects of the metal oxide surface structure and the stability and structure of metal clusters on the support are discussed as well as the reactivity of surfaces, including their behaviour upon poisoning. It is exemplarily ...
