metallic surfaces and polymers any reference?

Hi,

I am starting a new project and I think that It would be very usefoul if any of you can point me out some good references about Md simulations of polymers on metallic surfaces???

After my firts readings/thoughts about this topic some questions arose,  such as,   what is the: "rigth" size of the simulated surface or the most accurate/proper geometry: cubic, othorombic..., about the  the metal/crystal surface , what plane do you selct to cleavege the crystal.  00-1, -100.....???

any comment is welcomed

thanks for reding
