title: Adsorption and phase transitions in adsorbed systems: structural properties of CCl4 layers adsorbed on a graphite surface.
abstract: We present the results of simulations of a CCl(4) monolayer adsorbed on a graphite surface. The CCl(4) molecule was represented either by a shapeless superatom or by its atomic sites. The simulations were carried out over a large range of temperatures, from 20 K up to 340 K. We address the following problems: (1) the influence of molecular shape on the structure and stability of phases (particularly at low temperatures), and (2) the influence of the graphite corrugation on layer stability and mechanism of phase transitions. In particular, we discuss the possibility and conditions of the appearance of hexatic phase in the system.
