I'm building multilayer structure. I build the heterostructure importing the the to phase of structure in VESTA
File -> New structure -> Phase -> Import
Now I want rotate second layer of the structure (e.g. 30∘). VESTA has a rotation matrix in Unit -> Transform
What is the form of this matrix? In case that I want make a matrix for an arbitrary angle (e.g. from 0∘ to 30∘) `
Last, and not less important. When I have the two structures and I export (e.g. VASP) only one of two is exported, the other is ignored.
How can I export all atoms of the heterostructure to fractional coordinates file (VASP POSCAR)?
