A conducting tip is brought very close to the surface of the object of interest Some electrons can "tunnel" through the space between the object and the conducting tip, creating a current. The way current varies as the tip is moved across the surface is used to determine the shape of the surface.
What else can I help you with?
What do you call the instrument that allows us to see atoms?
The instrument that allows us to see atoms is called a scanning tunneling microscope (STM). It works by scanning a sharp tip over a surface at a very close distance to detect the electrons that tunnel between the tip and the atoms.
What is the shortest objective called in a microscope?
The shortest objective lens in a microscope is typically referred to as the scanning lens.
What is the maximum magnification for a scanning electron microscope?
The maximum magnification for a scanning electron microscope is typically around 1,000,000x. At this level of magnification, the microscope can resolve features as small as a few nanometers.
What is a scanning probe microscope?
A scanning probe microscope is a type of microscope that uses a physical probe to scan the surface of a sample to create images with very high resolution. It provides detailed information about the topography and properties of the sample at the nanoscale level. Examples of scanning probe microscopes include atomic force microscopes and scanning tunneling microscopes.
What is the lowest power of a microscope?
The lowest power of a microscope is typically 4x, known as the scanning objective lens.
Who invented the scanning tunneling microscope?
a scanning tunneling microscope measures electrons that leak, or 'tunnel', fromthe surface of specimen

Who invented the tunnel microscope?
The first scanning tunneling microscope was invented in 1982 by Binnig and Rohrer. They won the Nobel Prize in Physics in 1986 for their invention.

What has the author C P Gilmore written?
C. P. Gilmore has written: 'The scanning electron microscope: world of the infinitely small' -- subject(s): Pictorial works, Scanning electron microscope 'The unseen universe' -- subject(s): Pictorial works, Scanning electron microscopy
What type of microscope would be best to use to look at different cells or organelles?
scanning electron microscope
When was the scanning electron microscope invented?
The scanning electron microscope was invented in the 1960s. The first commercial scanning electron microscope was introduced in 1965 by Cambridge Instruments.
What are the various KINDS of a microscope?
Stereomicroscope, Compound Microscope, Phase-contrast microscope, electron microscope, Scanning-electron microscope, Transmission electron microscope, Confocal-scanning microscope. THESE ARE JUST SOME. :)
What is a SEM microscope?
A SEM microscope is a scanning electron microscope
What type of microscope can produce three - dmensional images of a cell's surface?
Scanning Electron Microscope (SEM)
Microscope that uses a beam of electrons?
A Scanning Electron Microscope
The microscope that allowed scientists to view molecules?
scanning electron microscope
