Hi Everybody I have started a project on naowires. I am doing experimental stuff but also intereted in some sort of simulations. Could any body tell me how the nanowires are formed when the atoms/molecules or clusters of atoms and molecules diffuse through the surface. I have searched the litratures a little but invain. I could not find an article about the theoratical detaild of nanowires. My concern is why nanowires are formed in diffrenet processed , why the atoms or molecules prefer to grow nanowires on surfaces as experimentalists have explained a little.
