Hello!
I want to use VASP for Nanoparticle simulation.
Can any one guide me how to start from the begining and what care should be taken during the calculations. I want to do calculations for TiO2 Nanoparticles to study its electrical properties. I know the bulk TiO2 has Rutile structue and i want to consider Rutile only.
I will be very thankful if you somebody gives me some useful tips and suggestions.
Thank you.

please set up the nanoparticle like a cluster (Gamma-only kpoint, small SIGMA, Gaussian BZ integration)

Thank you very much. But shold I increase K-points for DOS calculations as we do for other materials.

please define more clearly what 'nanoparticle' means in your case.
Small clusters have no 'band' dispersion and show discrete spectra (not a broadened DOS) therefore.
