Hello

I am quite new in using VASP,
and I wonder if any one can provide me an example with the information
to create the POSCAR file for the Ag(111) structure.
Any recoemendation about which GUI for vasp can work better to make similar
strucutres? Is any of the GUI free and working on Unix-Linux systems?

Many thanks
Oscar

for an example of the 111 surface of an fcc metal (Ni 1x1-cell, 5 layers + ca 12Ã… of vacuum), please have a look at the vasp-workshop excesises Nr. 3: you can download all inputs (including the POSCAR files) from our website (http://cms.mpi.univie.ac.at/vasp-workshop) example (.tgz) files of excercise session 3.
you will have to modify the overall lattice constant (3.53 for Ni) in the second line of POSCAR and, if requested, extend the 1x1 supercell to a larger one (change the Bravais Matrix and add the requested atomic positions).
