Abstract

Ce comportement est etudie par microscopie ionique a emission de champ sur les surfaces (100) et (111) d'Ir en fonction de la temperature. Determination des parametres de diffusion, l'energie de dissociation des atomes de la limite du plan, et d'autres parametres experimentaux. Analyse de l'energie de liaison des atomes a la surface. Observation d'une transformation d'une structure de 1 dimension a 2 dimensions pour les amas de 3 atomes. Cette transformation est differente sur les faces (111) et (100)
