Atomic Force Microscopy (AFM)
This technique allows the mapping of surfaces on a molecular or atomic scale. It can also be adapted to measure interatomic forces. The principle of operation of AFM is discussed as follows: A silicon or silicon nitride probe with a fine (approximately 1 nm radius) tip is connected to a flexible cantilever. The molecular or…
