The principle is shown in Fig. 6.30, illustrating how the invention arose from the perennial problem of capillary condensation in the fine gap between tip and surface. An atomic force microscope (AFM) tip is positioned close to a flat gold substrate. If the air is damp, then moisture appears in the very fine capillary gap
