This research monograph discusses the close correlation between the magnetic and structural properties of thin films in the context of numerous examples of epitaxial metal films, while emphasis is laid on the stabilization of novel structures compared to the bulk material. Further options, possibilities, and limits for applications are given. Techniques for the characterization of thin films are addressed as well.

It is known that some of the abnormal magnetic properties of ultrathin metal films, and their electrical conduction mechanism, can be explained on the basis of their "island" structure. It can be shown that the electrical conductivity and the temperature coefficient of resistance are controlled principally by the radius of the islands and the distances between them. By suitably adjusting these structural parameters, both of which enter the relation for the film conductivity exponentially, one can be made to predominate over the other. Thus, if the islands and the distances between them are small, very large negative temperature coefficients are observed. On the other hand, if the islands are very large or the thermal expansion coefficient of the substrate is unusually high, positive temperature coefficients can be observed, often several times larger than even the bulk values, even for films of resistances as high as 10 to the 6th power omega/square or higher.

Thin films of conducting materials, such as metals, alloys and semiconductors are currently in use in many areas of science and technology, particularly in modern integrated circuit microelectronics that require high quality thin films for the manufacture of connection layers, resistors and ohmic contacts. These conducting films are also important for fundamental investigations in physics, radio-physics and physical chemistry. Physical Properties of Thin Metal Films provides a clear presentation of the complex physical properties particular to thin conducting films and includes the necessary theory, confirming experiments and applications. The volume will be an invaluable reference for graduates, engineers and scientists working in the electronics industry and fields of pure and applied science.

Transparent electrodes (TEs) are a class of materials that make it possible to bring electrical current or potentials in close proximity to optically active regions without significant loss of optical energy. However, it is a challenge to decouple the electrical and optical properties of a material, as the property of conductivity is strongly coupled to the imaginary part of the refractive index. An ideal TE has high transparency in combination with very low electrical resistivity. The main objective of the thesis was to develop TEs which can replace expensive, scarce and fragile Indium Tin Oxide (ITO), the most widely used TE material in the industry today. The thesis contains original work on ultrathin metal film (UTMF)-based TEs, which are essential elements in a wide range of optoelectronics, consumer electronics and energy devices. It presents new designs and fabrication methods and demonstrates the efficient use of UTMF-TEs in organic light emitting diodes and solar cells, achieving similar levels of efficiency to that of state-of-the-art ITO.

This up-to-date handbook covers the main topics of preparation, characterization and properties of complex metal-based layer systems. The authors -- an outstanding group of researchers -- discuss advanced methods for structure, chemical and electronic state characterization with reference to the properties of thin functional layers, such as metallization and barrier layers for microelectronics, magnetoresistive layers for GMR and TMR, sensor and resistance layers. As such, the book addresses materials specialists in industry, especially in microelectronics, as well as scientists, and can also be recommended for advanced studies in materials science, analytics, surface and solid state science.
