Regular and irregular growth and dissolution of (101) ADP faces under low supersaturations

A technique has been developed to automatically measure normal growth rates as low as 3 × 10-9 cm/s and higher, the tangential growth rates and hillock slopes. The method was applied to the (101) ADP growth in the kinetic regime at various supersaturations 0.05% < σ < 2.5% and pH = 3.6−5.6. The direct incorporation model allows determination of the effective step free energy, ⋍ 8.5 × 10−7 erg/cm (corresponding to the surface energy of 16...
