Imaging of adenine and thymine at atomic resolution by the scanning tunneling microscope (CAT#: STEM-MIT-0321-LJX)

The basic principle of scanning tunneling microscope (STM) is to use the tunneling effect in quantum theory. An extremely fine probe of atomic linearity and the surface of the substance under study are used as two electrodes. When the sample is very close to the tip of the needle (usually less than 1nm), electrons flow through the barrier between the two electrodes to the other electrode under the action of an applied electric field. This phenomenon is known as tunneling effect.
