Silver-copper alloys are condensed in a liquid-solid domain of the phase diagram on a tilted
molybdenum substrate regulated in temperature. After a droplets regime, a film which contains a
monolayer of nodular solid crystals forms. The size distribution and density of the particles in the film are measured after different condensation times. Results show that in our experimental
conditions a ripening process occurs which is evidenced by a decrease of the number of particles
with time, and a broad particle size distribution. However, the decrease rate is smaller than
expected without a condensation flux. A model is then developed to interpret and generalize these
results. This model results from the modification of the Lifshitz-Slyosov model [1] to take into
account the supply from the vapour phase. It is shown that the higher the flux of material to
solidify from the vapour phase is, the more the growth from the vapour phase overcomes the
ripening process. Once the particle density reaches a characteristic value which is simply
proportional to the incoming flux, no more particles are dissolved. The system then tends towards
a monomodal distribution with a radius which grows in t1/3.
