Hi i am new to CDW concept and could not find any tutorial on CDW calculations in VASP for monolayers.

Can you kindly share a relevant tutorial link as a start up.

Hi,

The key point is to consider a simulation box that is large enough (i.e. a supercell) to accommodate the charge density waves. A quick search for works on CDW that provide some details are for instance
https://doi.org/10.1021/acsnano.4c15914
https://doi.org/10.3390/nano12030504

The construction of a supercell can be done with the VESTA program (https://jp-minerals.org/vesta/en/), for which several tutorials on youtube are available.
