There are few steps to make AFM.
- First make nanometer size tip ✅
- Power supply ✅
- Make it vibrate up and down
- Measure the force of vibration/input
- Coarse XYZ movement of sample
- Fine XYZ movement of AFM tip - electrical part ✅
- Fine XYZ movement of AFM tip - mechanical part
(Probably there are more steps, we will uncover them as project continues)
XY movement has a very good explanation in Lego2Nano with electric schematic and software algorithms.
For force measure we will use Quartz fork instead of laser one.
