QE Tutorial 8 | How to calculate charge density

In this tutorial (QE Tutorial 8), I demonstrate how to calculate and visualize electron charge density using Quantum ESPRESSO. Using graphene as an example, I explain: How to obtain electron charge density from self-consistent field (SCF) calculations Generation of 3D charge density Extraction and visualization of 2D (planar-averaged) charge density Practical use of post-processing tools like pp.x Interpretation of charge density plots for low-dimensional materials This video is especially useful for students and researchers working on DFT calculations, 2D materials, and electronic structure analysis using Quantum ESPRESSO. 📚 This tutorial is part of an ongoing Quantum ESPRESSO learning series, aimed at helping beginners understand DFT concepts through practical examples.
