Structure formation mechanisms of low-dimensional porous systems are explained on the ground of different growth rates at local condensate areas and partial coalescence of the structural fragments. By means of scanning and transmission electron microscopy the formation mechanisms of porous Ti condensates on glass and KCl cleaved facets are studied. It is shown by the example of self-assembly of porous Ti layers that the factors underlying such process are self-organization of time-constant critically low effective supersaturation and continuous sequence of interdependent structure and morphology changes of the growth surface that cause the appearance of active centers for attaching adatoms.
