On the prediction of crystal morphology. III. Equilibrium and growth behaviour of crystal faces containing multiple connected nets

In this paper, the equilibrium and growth behaviour of faces (hkl) with mor e than one connected net is studied. It is shown that for these types of or ientation different surface phases exist under equilibrium conditions as a function of temperature. Depending on the exact bonding topology at the sur face, hat, rough or disordered flat phases are found. Moreover, the growth rate R-hkl of such faces can differ significantly from the usually calculat ed relative growth rates based on the attachment energy. Monte Carlo simula tions confirm the results from the Hartman-Perdok analyses and offer a tool for the prediction of the crystal habit as a function of supersaturation.
