ABSTRACT
In this letter, we present a promising scanning probe microscopy mode, called combined dynamic X mode or short CODYMode®. In CODYMode® scanning force microscopy, at least two modulations with sufficiently different frequencies and amplitudes are superpositioned and interact with the sample surface. This enables the concurrent measurement of the topography, adhesive and frictional forces, and further mechanical surface properties of the sample. The general advantages of CODYMode® are discussed. This technique is predestined for investigation of delicate samples (polymers, biological samples, etc.) in which common scanning force microscope techniques are not adequate. An ABC-triblock copolymer system served as sample system. © 2000 American Institute of Physics.

    In this article, we propose a technique for highly stabilized atom-tracking control of a scanning tunneling microscope (STM) tip by referring to an atomic point on a regular crystalline surface. Our aim is to prevent jumping of the STM tip to neighboring atoms and to use it even in a noisy...

    Firstly, both the rest atoms and the adatoms of Si(111)-7×7 surface are observed simultaneously by scanning tunneling microscopy (STM) when the sample bias voltages are kept less than - 0.7V. The visibility of the rest atoms is rationalized by first-principle calculations and a very sharper...

    Gold and lead clusters were grown by the evaporation of metal atoms on rare gas layers on Au(111) and Pb(111). The growth was investigated with scanning tunneling microscopy (STM) and ultraviolet photoelectron spectroscopy (UPS). We studied the electronic coupling to the surface and charging...
