Tutorial 1

Tutorial 1. BN (semiconductor). Band structure

The classes hosted in the qepy folder are useful not only to execute Quantum Espresso but also to analyze the results.

Plot Band structure

The class PwXML reads the data file generated by Quantum Espresso and post-process the data.


Band structure of BN calculated at the level of DFT-LDA


Plot atomic orbital projected Band structure

Atomic orbital projected band structure of monolayer BN

Tutorial 2

Spin polarized band structure of iron calculated by DFT


Iron band structure. Size is proportional to the weights of the projection on atomic d-orbitals. Red (blue) is up (down) spin polarization.
