DFT Modules

What kind of data do you need?

Density Functional Theory(DFT) aims to obtain the ground-state electronic state of materials.
Get information about ground-state energy, lattice parameter of the optimized structure and electrical properties of materials.

Band Structure

You can get the band structure of materials, which can be used to characterize the band gap of the system.

To get band structure in MatSQ ⇢

Density of States

Atom and orbital-projected density of states and the entire density of states of the system can be analyzed. This analysis can be used for example investigating the effect of the defect on the electron structure of the magnetic properties of the system.

To get DOS in MatSQ ⇢

Charge Density

You can conveniently find and visualize the charge density data by carrying out a plane-wave basis DFT calculation of Quantum Espresso.

Phonon

You can get the band structure of materials, which can be used to characterize the band gap of the system.

To get phonon in MatSQ ⇢

Energy Comparison

The energies of different calculations can be visually compared. This comparison will enable you to friendly the most probable adsorption site on surface or the equilibrium dopant position.

MatSQ Simulation Tip #26

Hybrid Functional
2019-10-16 07:57:57

GGA has a fundamental characteristic underestimate band gap, Hartree-Fock has an overestimate band gap. This is due to the exchange potential approximation, so if mix both functionals, enable correcting band gap and other electronic structures. Read more

MatSQ Simulation Tip #25

Van der Waals Correction
2019-10-08 04:38:16

Van der Waals Correction is performed to improve the precision of GGA. Van der Waals Correction, such as DFT+D3, corrects the correlation term of exchange-correlation potential by adding dispersion term. Read more

MatSQ Simulation Tip #24

DFT+U
2019-09-27 01:55:42

DFT+U is a correction method for the correlation energy caused by the mean-field approximation. When electrons fill in an orbital, the energy differs based on whether the other electron exists in the orbital. Read more
