Question 1.
What does AFM stand for?
Show hintHide hint
Think of force and microscopy together.
Question 2.
What does the tip on an AFM do?
Show hintHide hint
A sharp tip to detect features.
3Question 3.
What principle does AFM rely on for imaging?
- Electric current
- Laser deflections
- Surface interactions
Show hintHide hint
Focus on how the tip interacts with the surface.
4Question 4.
True or False: AFM can only be used in a vacuum.
- True
- False
Show hintHide hint
Think about the environments you might want to study.
Question 5.
Design an experiment using AFM to analyze the surface roughness of a newly synthesized nanomaterial. What considerations would you have to take into account?
Show hintHide hint
Reflect on the specific attributes you need to image and measure.
Question 6.
Discuss the impact of cantilever spring constant on AFM measurements. How does changing this affect data acquisition?
Show hintHide hint
Think about how sensitivity and force interactions relate.
