Aluminum (Al) was deposited on multiwall carbon nanotubes (MWNTs) with mean thicknesses ranging from 1 to 11nm in vacuum, and the influence of deposited Al on field electron emission was investigated by field emission microscopy (FEM). Al deposition significantly suppressed fluctuations of emission current after a simple conditioning process. Interestingly, FEM images revealing atomic detail of an Al cluster with the cubo-octahedron structure were observed. Discussion on the spatial resolution in FEM for MWNTs suggests the probable observation of some atomic structures with a resolution of the order of 0.3 nm.
