ADP crystal shows different kinetic mechanism of growth from solutions . In "situ" macroscopic growth rates of prismatic and pyramidal faces were measured (+/- 0.01 mm accuracy) versus supersaturation (s). After seed regeneration, a transient regime of growth was found for the prismatic faces of ADP. Within a fresh grown layer, smaller than 1 mm, the growth efficiency decreases 3 to 6 times and it is 6 to 12 times higher than for the elementary dislocation . Data compare well with interferometric measurements of Chernov et al . Edge free energy on prismatic faces of ADP was estimated as 0.84 kT.
