Scanning Probe Microscopes can image the surface of
a sample by measuring the interaction between the atoms on the sample surface
and an extremely sharp probe tip, which is produced by micro machining. SPM can
magnify the surface over 10 million times, making it possible to image
individual atoms. SPM can be operated in air as well as in a vacuum, while
electron microscope can be operated only in vacuum. |

Not only can SPM image the topography of the sample surface, but also can
measure its electrical, magnetic and physical properties. For its unprecedented
high resolution and versatility, SPM has made a profound contribution in many
areas of research, including materials science, surface analysis, polymers,
nanotechnology and biology. |
