✦ Synopsis

Phase imaging is one of the most attractive features of tapping mode scanning force microscopy operation. In this paper we analyse the relationship between phase contrast imaging and the energy loss due to tip-sample interaction forces. An analytical relationship is obtained between the phase shift and the energy loss. Experiments performed on graphite are in agreement with the analytical expression.
