IMPORTANT NOTE: In installation on ubuntu, I recommend to install 6.4 version of quantum espresso instead of 6.6 version. I mean install q-e-qe-6.4. The installation method in both version is similar. Just download 6.4 version instead of 6.6 (step 4 of quantum espresso installation)

Install quantum espresso on windows using oracle VM virtual box and the quantum mobile image, or alternatively create an ubuntu desktop in virtual box and install quantum espresso there.
Study essential quantum espresso calculations with graphene as a case study. Learn input file structure, lattices, pseudopotentials, energy cutoff and kpoints, and perform SCF, vc-relax, DOS, bandstructure, and phonon calculations.
Perform a four-step phonon calculation using Quantum Espresso: SCF, build dynamical matrices with PWGUI and ph.x, compute IFCs with q2r, then obtain and plot phonon dispersions with matdyn.x and plotband.x.
Explore silicon as a case study by executing eight main calculations—scf, vc-relax, relaxation, density of states calculation, charge density calculation, bandstructure and projected bandstructure calculation, and phonon calculation—using Quantum Espresso.
In this course, the quantum espresso software is fully taught, and its various calculations are discussed. Calculations such as self consistent field (SCF), density of states (DOS), Band-structure and projected band, charge density and wave functions, phonon, etc. We also learn how to find the optimized lattice vectors and atomic coordinates by using variable cell relaxation (vc-relax), and ionic relaxation.
In this course, we tried to explain all the details of this software. Even the installation methods are fully explained. To obtain a deeper understanding of these calculations, various examples are given on different lattices such as graphene and silicon. The method of each calculation is taught using flowchart and all variables are examined. This course is not just a software tutorial. Indeed, in each lecture, the physical basis of these calculations is explained such as lattice structure, pseudopotentials, reciprocal lattice, etc.
At the end of this course, you will have a complete understanding on quantum espresso calculations. Also, you can extract the electronic and physical properties of materials. This course is useful for quantum physics students, materials specialists, nano and micro electronic engineers, semiconductor companies, etc. You may use it for your studies, paper, thesis, and every day to day jobs.
