Other advantages of the scanning tunneling microscope include:
The two major downsides to using STMs are:
Low cost and relatively low quality STMs start at approximately $8,000 but some people have actually built their own amateur STMs for much less than that amount.
However, professional quality STMs can range anywhere from $30,000 to $150,000 depending on the manufacturer and the extra parts included.
ManufacturersIf you are interested in buying a scanning tunneling microscope, there are several reputable manufacturers from which you can make a purchase.STM manufacturers include:
The scanning tunneling microscope scans samples using a very fine metallic tip.
Needle in the scanning tunneling microscope is about 10 nanometers.

The needle doesn't actually touch the atoms, but you can their outlines.
I think that it comfirmed the long held suspicion that you can see paterns in matter. I'm not sure what the tunneling microscope does.

In 1981 the Scanning Tunneling Microscope (STM) was invented. The STM has ultrahigh resolution and can image single atoms.
