Abstract : The ring structures and dynamic phenomena observed in field ion microscopy with negative ions NFIM of tetracyanoethylene TCNE are interpreted as ion images of a surface layer grown by field-induced polymerization of the image gas molecules. The ring structures are attributed to the formation of mobile surface elevations by the field stress on the polymer layer. These small surface elevations combined with larger surface deformations, generated by the field stress and resulting from elastic properties of the bulk of the layer, explain many features of NFIM such as the clustering of rings and compression of ring structures.
