Abstract
Experiments on water droplets condensing on a liquid substrate (breath figures) are reported. Attractive capillary interactions between drops lead to the formation of particular two-dimensional structures. An hexatic order with exponent η≊0.9 is observed over a small length scale. At larger length scales the defects in the structure exhibit a fat-fractal distribution with exponent β≊3.3.Keywords
