The tip of the STM (yellow) assumes the role of a hard drive's reading and writing head for the molecule attached to the copper nitride surface (black).

With the STM, resolving atoms within an adsorbed molecule is difficult because the ... with an amplitude of 0.2 Å, at a constant height above the surface and measured how the force on the tip ...

This is an illustration of a buckydiamondoid molecule under a scanning tunneling microscope (STM). The sharp metallic tip of the STM ends in a single atom; as it scans over a sample, electrons ...
