Plateau’s law describes the configuration (joint angles ~120°) of soap bubbles, foams and cellular structures, but its applicability to solid films has not been explored. Here, the authors report the observation of a variant Plateau’s law in networks of nanobubbles made of 2D semiconductors, measuring largely varying joint angles due to the thickness-dependent effective surface tension.
