The STM uses a tip that ends in a single . It was generated in 1981 by Gerd Binning and Heinrich Rohrer of IBM's Zurih Lab in Zurich,Switzerland. The STM sample must conduct electricity for the process to work. They then Carbon nanotubes, an important nanotechnology structure, are very stable and may serve as insulators, conductors, or semiconductors depending on how they are produced.

The scanning tunneling microscope (STM) works by scanning a very sharp metal wire tip over a surface. The Scanning Tunneling microscopy allows researchers to collect and study images at an atomic level, and they can also alter the environment to yield different results. A scanning tunneling microscope (STM) is a non-optical microscope that works by scanning an electrical probe tip over the surface of a sample at a constant spacing. The Scanning Probe Microscope - Advantages and Disadvantages in Microscopy Scanning tunneling microscopes allow nanotechnology researchers to individually look at and work with atoms.
