Abstract
A method based on the detailed analysis of tip changes is proposed for the
investigation of tip cluster structure. As proposed by Mizes et al [7] the
tunneling current for a multiple tip is considered to be produced by the
superposition of currents corresponding to the individual tip atoms. Good
agreement is found between experimental results for PtIr tips and computer
simulations for a Pt15 [110] tip cluster. From the modification of the acquired
image during imaging HOPG the modifications of the tip structure may be
inferred.
