Background and History
- 1st AFM made by Gerd Binnig and Cristoph Gerber in 1985
- Constructed by gluing tiny shard of diamond onto one end of tiny strip of gold foil
- Small hook at end of the tip pressed against sample surface
- Sample scanned by tracking deflection of cantilever by monitoring tunneling current to 2nd tip position above cantilever
- Developed in order to examine insulating surfaces
