Studies of Thin Film Nucleation Kinetics (Island Growth)
Thin film nucleation theory for the island growth model has long been a subject of intensive study because understanding of the nucleation mechanisms should improve the attainable film morphologies. In spite of the long history of nucleation theory, the current status of the theory is not able to …

Epitaxy of Self -Assembled Nanostructures by Metalorganic Chemical Vapor Deposition
… better suited for self-assembled nanostructure growth and processing, but single island growth with resolutions on the order of 100 nanometers have been achieved.

Metallic thin film on SiGe/Si substrates
… substrate (VS), the interfacial reaction and growth mode of Ni thin film on Si0.8Ge0.2 VS at room temperature (RT), and the germanosilicide phase transformation at high temperatures. Similar studies on Si(001) and Ge(001) substrates were also carried out for comparison. The Si0.8Ge0.2 VS …

X-ray studies of metal thin film growth on semiconductors
… on Si(111)-(7 × 7) at 180 K reveal an unusual growth behavior. A wetting layer forms first to cover the entire surface. Then islands of a fairly uniform height of about five monolayers form on top of the wetting layer and grow to fill the surface. The growth then switches to a layer-by-layer …

Optical Properties of Organic Semiconductors: from Submonolayers to Crystalline Films
… mica, glass, and HOPG. Extrinsic effects due to island growth or the presence of a polarizable substrate (screening) have been accounted for. We have introduced a finite dipole model which considers the extended geometry and anisotropy of the organic molecules. The calculated absorption behavior …

High moment shield structures for improved linear density capability in thin film recording heads
… Disk Drive (HDD) Areal Density Capability (ADC) growth is improving the linear resolution of the reader. Increasing reader shield saturation magnetisation is an attractive means to enable this as dynamic permeability would be expected to improve, thereby providing greater shielding from …

A variable temperature scanning tunneling microscopy study of organizing C60 molecules on nanostructured gold surface
The nucleation and growth of C\(_{60}\) molecular nanostructures on the Au (111) surface are studied under various conditions using variable temperature UHV STM. At room temperature, the C\(_{60}\)/Au interface exhibits rich features observed in the STM images, for instance the lifting of the …

Fabrication and characterization of multilayers for focusing hard x-ray optics
This study investigated the growth of multilayers with depth-graded thicknesses and their performance as x- ray mirrors for the next generation of focusing telescopes. Different material combinations were studied for the first time employing a consistent methodology for the DC magnetron sputtering …

Diffusion and growth of steps and islands on surfaces
… of surface structures even on atomistic scales. Growth of metal and semiconductor crystal surfaces requires accurate growth techniques, among which Molecular Beam Epitaxy (MBE) has a special status since it can be very efficiently used to produce growth in well defined layer-by-layer growth mode. …

Photocatalyst testing and development
… for demisting purposes. A study of Ag-particle growth on sol-gel TiO2 films demonstrated the necessity of overlapping island growth of the Ag-particles to enable conduction.

Hochauflösende Rutherford-Streuspektrometrie zur Untersuchung von ZrO2-Schichtwachstum im Anfangsstadium
Die vorliegende Arbeit entstand im Rahmen einer Kooperation des Forschungszentrums Dresden-Rossendorf mit Qimonda Dresden GmbH & Co. OHG. Mithilfe der hochauflösenden Rutherford-Streuspektrometrie (HR-RBS) wurden das Diffusionsverhalten und Schichtwachstum von ZrO2 auf SiO2 und TiN im …
