✦ Synopsis

Ligand-stabilized clusters were prepared on Au(111) surfaces and investigated by electrical force microscopy Au 55 (EFM) in dynamic non-contact mode, which allows the detection of d.c. potential di †erences between tip and sample as well as the tip-sample capacitance. This work explains the measurement procedure and presents the observed C(U) characteristics of the special sample system.
