Buckling Nanotube
Michael Stadermann
Michael Stadermann, a physicist at the University of North Carolina at Chapel Hill, used a pioneering technique called conductance-imaging atomic force microscopy to image this carbon nanotube resting on a silicon dioxide surface, next to a smattering of gold atoms. The technique measures a sample's topography and conductance simultaneously: Superimposed in the image on the topography, the conductance appears as color -- the brighter the color, the higher the conductance. Merging the different properties of the object into one image could provide clues as to how they interact.
