The dynamics of surface atoms and simple molecules is closely related to the growth of surface nanostructures. The questions we ask are how atoms diffuse and interact on the surface and what kind of surface nanostructures are formed from such interactions. We also study how the physical property...

In nanoscale, gas density is not really homogenous even in thermodynamic equilibrium especially in a region near to the domain boundaries due to the wave character of gas particles. This inhomogeneous region is called quantum boundary layer (QBL) since its thickness goes to zero when the...
