Unformatted text preview: 7. MEA a. The three modes are the contact mode, the noncontact mode and the tapping mode. The advantages of all the modes are that they map the tomography of the surfaces, but the disadvantages of them are that in the contact mode is that it can damage sample surfaces. The disadvantage of the tapping mode is that it has the lowest surface force. b. The AFM resolution limit is between the tip and the surface feature of the sample. c. The shape and radius of the cantilever tip is what limits the resolution of the AFM....
