ac mode AFM images of water droplets nucleation and growth on (001) single crystal domain surface at 85% RH after: (a) 16 min (3 nm Z scale) and (b) 120 min exposure (12 nm Z scale). The same region is outlined in both images.
Water droplet height time dependence at 85% RH. Inserts show surface topography with the same area outlined.
(001) surface topography images (80 nm Z scale) of domain corrugations in (a) dry Ar and (c) at 95% RH; (b) and (d) are corresponding amplitude images with potential profiles in mV superimposed.
EFM images of original and domain corrugations on (001) surface acquired in (a) dry Ar (1 V Z scale), (b) after 30 min 65% RH exposure with corresponding potential profiles in mV superimposed (50 mV Z scale).
(100) and (001) surface energy before and after water adsorption with corresponding adsorption energy . is molecule energy.
