We study in detail the dynamics and range of their relaxation/diffusion along the growth plane, asa function of temperature. %G English %2 https://hal.science/hal-01305161/document %2 https://hal.science/hal-01305161/file/Poster_Fedichkin_Compound_Semiconductors_Montpellier_2014.pdf %L hal-01305161 %U https://hal.science/hal-01305161 %~ CNRS %~ OPENAIRE %~ L2C %~ MIPS %~ UNIV-MONTPELLIER %~ UM-2015-2021
