The absolute measurement of free energies associated with crystal steps on a metal surface has been a long-standing problem. We report a reliable estimate of the step free energy on a Cu(111) crystal surface, based on an analysis of island shape fluc

The successful experimental implementation of a powerful concept for the determination of energies controlling ripening and annealing on surfaces is reported. On a Ag(111) surface, we have prepared and studied the decay of well-defined nanostructures

Conventional and manipulated molecular beam epitaxy (MBE) of Ni on Cu(111) was studied by helium atom scattering and low-energy electron diffraction over a wide temperature range. During conventional MBE at low temperatures, three-dimensional rough g

The reshaping of two-dimensional vacancy islands during coalescence has been studied experimentally on a Ag(111) surface at room temperature using a fast scanning tunneling microscope. Different stages of the coalescence event have been found: the in

We have investigated the decay of two-dimensional (2D) islands on the anisotropic Ag(110) surface using variable-temperature scanning tunneling microscopy. Contrary to predictions from traditional Ostwald ripening theory, a quasi-one-dimensional (1D)

We describe experimental problems arising with the continuous observation of nanostructure dynamics by STM. We discuss the necessity to use a high-speed STM, possibilities to deal with the thermal drift, and tests to rule out the influence of the sca

On the basis of a kinetic growth model we discuss new methods to grow atomically flat homoepitaxial layers in a controlled way. The underlying principle of these methods is to change the growth parameters during growth of an atomic layer in such a wa

Rocking curves acquired with thermal energy He-atom scattering indicate that for small 2D Ag islands grown on Ag(100) at 200 K, the apparent step height normal to the surface is reduced by about 0.6 A compared to the step height calculated on the bas

It has been reported that the growth mode or Ag on Ag(111), which is usually multilayer (3D), changes to layer-by-layer (2D) growth if Sb is used as a surfactant. In a model study on the clean system Ag/Ag(111) (without any surfactant) we find that t

The initial stages of growth of Pt on Pt(111) have been investigated as a function of the substrate temperature. The main result is that, while between 200 and 400 K the cluster density decreases with increasing temperature in accordance with nucleat
