We present experimental investigations of two-dimensional crystallization of calibrated Brownian spheres in water. The interaction monitored by an external AC electric field is attractive in a wide range of frequency and leads to a clustering of fractal crystallites. The fractal dimension of the structure is measured to be D = 1.74 ± 0.05 in good agreement with the theory of dynamical clustering of clusters. Melting occurs upon increasing frequency and is continuous via a phase of hexatic symmetry as seen by light scattering.Nous présentons une étude expérimentale de cristallisation bidimensionnelle de sphères de latex calibrées, Browniennes en suspension dans l'eau.
