Phonopy k-path for 2d structure
WebTo find the k-path of the surface you have to use the k-path of the obtained surface. Let's take the 111 cut of FCC. In this case, we get hexagonal shape of the surface. http://grandcentral.apam.columbia.edu:5555/documentation/phonopy/phonopy.html

WebNov 19, 2024 · SET UP CALCULATIONS: Create a folder with the desired POSCAR unit cell. Decide on the size of supercell to do calculation on. For example, 2 x 2 x 2. Generally we aim for a supercell that has similar a, b, and c lattice vector lengths. In command line, enter: phonopy -d --dim="2 2 2". This writes out a series of new POSCAR files.
