Le terme "AFM" évoque souvent des images de paysages microscopiques, révélant les détails complexes des surfaces à l'échelle nanométrique. Bien que la microscopie à force atomique (AFM) soit en effet un puissant outil d'imagerie, ses applications en génie électrique vont bien au-delà de la simple visualisation.
Au-delà de l'imagerie : la polyvalence de l'AFM
La polyvalence de l'AFM réside dans sa capacité non seulement à imager, mais aussi à manipuler des matériaux au niveau atomique. Cela ouvre une vaste gamme de possibilités pour les ingénieurs électriciens, leur permettant de :
