Problem about calculating CO adsorption
Dear friends,
Thanks very for your attention.
I'm trying to calculate the adsorption of CO on SnO2 surface. Firstly, I relaxed the ideal SnO2(110) surface. Then, I put a CO atop the surface. A weird thing happened: The CO molecule seems extremely unstable. The C or O atom jumped out of the supercell lattice. I tried several jobs with different CO initial positions, but the problem kept happening. Then I tried to calculate single CO and CO2 molecules. Again, the C or O atom jumped out of the lattice box.
Could somebody tell me what's the problem? Why does CO or CO2 molecule seem so unstable in a periodic box?
Thanks very much
