Scanning tunneling microscope vs. scanning electron microscope

The scanning electron microscope (SEM) is capable of imaging an object with a resolution of better than one nanometer. To put that in perspective, a meter is to the size of the earth as a nanometer is to the size of a marble. A nanometer, at the small limit of ...
