This is a problem related to the nanoscale manipulation.
- Please compare various manipulation methods, STM, AFM, opticaltweezer, and magnetic tweezer in terms of force magnitude.
- Describe the physical principle of the optical tweezer fortrapping an atom.
- Try to think and write down the possible difficulties andchallenges you will face when you perform the manipulation on asingle nanostructure.
