Strain-induced properties of epitaxial VOx thin films
We have grown VOx thin films on different substrates in order to investigate the influence of epitaxial strain on the transport properties. We found that the electric conductivity is much larger for films grow...

Epitaxial growth of solution deposited YBa2Cu3O7-δ films
The solution deposition of YBa2Cu3O7-δ (Y123) high temperature superconducting thin films was studied. The films were prepared from a polymer-containing precursor onto SrTiO3 (001) and LaAlO3 (001) substrates ...

Epitaxial growth of solution deposited Bi \(_\mathsf{2}\) Sr \(_\mathsf{2}\) CaCu \(_\mathsf{2}\) O \(_\mathsf{x}\) films
The epitaxial growth of Bi2Sr2CaCu2O x (Bi2212) high temperature superconducting thin films was studied. The films were solution-deposited from a polymer-containing precursor on...

Characterization of anti-phase boundaries in epitaxial magnetite films
The occurrence of anti-phase domain boundaries (APBs) in epitaxial Fe3O4 films has a strong influence on the resistivity, magnetic and magneto-resistance properties of these films. It is therefore important to un...

MBE-Growth of Iron and Iron Oxide Thin Films on MgO(100), using NO2, NO, and N2O as Oxidising Agents
We have made a study of the use of NO2 as the source of oxygen in the MBE-growth of iron oxides thin films. It is found that NO2 is a much more efficient oxidising agent than molecular O2. As indicated by Mössbau...

Growth and properties of epitaxial iron oxide layers
Epitaxial layers of iron oxides have been grown on a MgO(001) substrate by evaporating natural Fe or57Fe from Knudsen cells in the presence of a NO2 flow directed to the substrate. The resulting layers have been ...

Scanning Tunneling Microscopy Imaging of Defects in Layered Compounds
Structural features of TiS2 were studied by scanning tunneling microscopy (STM) and single-crystal X-ray diffraction was applied as a complementary technique. STM images in air and at room temperature revealed, b...

Critical Misfits for Lattice-Matched Strained Monolayers
Epitaxial thin layers or multilayers can now be grown with a high degree of perfection using ultra high vacuum evaporation techniques. Although it is still in general difficult to predict which material can be...

Electronic Processes in Polymeric Dielectrics Under High Electrical Fields
Compared to metals and semiconductors, the electronic properties of insulators in general, and of polymeric insulators in particular, are only poorly understood. Most important manifestations of nonideal insul...

Effect of Relaxation on some Thermodynamic Properties of Lattice Gas Models with Applications to AgCrS2 and Hollandite
Recently, various aspects of interacting particles moving in a periodic substrate potential have been investigated. Many papers have considered the commensurate-incommensurate transition within various restric...

Local Order in the Solid Electrolyte α-HgAg2I4
Until now very little is known about the influence of correlations between conduction ions on the conduction mechanism in solid electrolytes. From diffuse X-ray studies the average positional pair correlations...

The State of Order of the Conducting Ions in Hollandites
In strictly one-dimensional channel structures ionic motion over any macroscopic length is very likely to be impeded by crystal faults and impurities. We have found that even in optically perfect single crysta...

The Gradual Order-Disorder Transition in PyAg5I6
The specific heat of PyAg5I6 shows two features: (1) A first order phase transition at ~220°K. The low temperature structure is multiple and consists of a small monoclinic distortion of the hexagonal unit cell at...
