Nucleation of single molecular layers

Single molecular layers nucleated and propagating over crystal surface at low supersaturation \(\sigma=\)0.051 and low nucleation rate. Timelapse movie of average subtracted RICM images at 0.1 s interval.  The dark areas correspond to a smaller distance to the confining glass and thus to the newly formed single molecular layer 0.33 nm thick. The four nucleation events originate at different locations. The crystal is 160 X160 \(\mu\)m.
