(a) Schematics of the experimental approach developed in this work. If the nucleation critical distance and the condensation time are approximately constant within a small range of approach speeds, we expect the meniscus to be formed at progressively smaller tip-sample distances with increasing tip-sample approach speed; (b) force distance curves at different approach speeds acquired with the FFM. The instant when the meniscus is formed is characterized by a vertical jump in the force. Note that there is a slight overshoot characteristic of feedback systems, that, however, does not compromise our measurement.
