Abstract

Two-dimensional first-order phase transitions of molecules adsorbed on homogeneous surfaces often proceed via nucleation and growth processes. In the present paper, a mathematical model is developed which takes into account the simultaneous processes of adsorption of the molecules from the bulk, surface diffusion of the adsorbed molecules and their consumption at the edge of the growing nuclei. From the numerical solutions of the model equations, several regimes of the process of nucleation and growth can be obtained depending on the ratios of the system parameters. The existence of these different growth regimes is provided experimentally in the 5-bromocytosine-mercury system.
