Concept explainers
(a)
Interpretation:
The two most common types of SPMs and the difference between them are to be stated.
Concept introduction:
The scanning probe microscopic has enough capability to resolve the details of the surfaces down to the atomic level. The scanning tunneling microscope is the first example of the SPMs. After the scanning tunneling microscope the second type of SPMs is atomic force microscope.
(b)
Interpretation:
The advantages of scanning tunneling microscope and the atomic force microscope are to be stated.
