Dear xcrysden users,
I am using PWSCF for BaTiO3 thin films
calculation, I just wanted to visualize the (110) surface of the same by
xcrysden. I am pasting the input PWSCF file for the same, the problem is my
system is monoclinic but xcrysden is showing it to be cubic, may be I am
doing some mistake. Please anybody help me out to fix the problem. The
calcualtin is for one layer.
Sincere thanks in advance,
Mohnish
