Having established that nucleation is easier on surfaces with defects when the surface does not strongly interact with the fluid, we now investigate how the groove width affects nucleation pressure in the low interaction limit. To nullify any potential effect of periodic BCs, we use a large simulation box as described in the third row of Table . The depth of groove is fixed at 12.24Å while exploring the effect of width. Our results indicate that nucleation is a two stage process, as shown in Figure . Stage 1, corresponds to the barrier associated with groove dewetting.
