Atomic force microscopy/ scannig force microscopy/ mikroskopie atomárních sil
1986 further improvement of STM
Suitable also for insulants, biological samples (very popular in live cell imaging)
Various modes
Non-contact
Tip oscillating in small height over sample, influences from forces (VDW, TC) – change of amplitude
Piezo – changing the oscillation magnitude via voltage change
Laser as optical leverage (500x feedback gain)
