Thin-film metallized dielectric waveguides
Soviet Journal of Quantum Electronics, 1975An experimental study was made of the influence of metallic and dielectric coatings on the propagation of selectively excited TE and TM modes in thin-film dielectric waveguides. The theoretical and experimental results were obtained for different metals and different waveguide thicknesses.

Dielectric susceptibility of ferroelectric thin films
Ferroelectrics, 1994Abstract The susceptibility profiles of ferroelectric thin films were calculated for the case when the bulk phase transition is first order. The dependence of mean susceptibility on the film thickness was discussed. When the polarization near the surface is reduced, the mean susceptibility increases with the decrease in film thickness and goes up ...

Thin Film Dielectric Ion Sensors
Journal of The Electrochemical Society, 1993A new type of ion sensor was developed. Thin film perovskite materials such as BaTiO 3 were deposited onto a metal electrode by a hydrothermal-electrochemical method in an autoclave. The resultant electrode was paired with a counterelectrode and immersed in solution.

Dielectric Properties of NaYF4 Thin Films
Physica Status Solidi (a), 1987The dielectric properties of thin film MIM structures of NaYF4 are extensively investigated in the frequency range 100 Hz to 16 kHz and in the temperature range 77 to 450 K. The capacitance and loss tangent of these films is found to be dependent on frequency and temperature.

Depth Profiling in Thin Dielectric Films
Critical Reviews in Analytical Chemistry, 1991Abstract Thin polymer films occupy an eminent position in modern science and technology both in and of themselves and as models for bulk polymer systems. Much of their function depends on their interaction with external (often hostile) environments. Thus, methods for obtaining information about the chemistry of these films as a function of depth are a ...

Selection of thin film capacitor dielectrics
Thin Solid Films, 1968Abstract Practical properties of thin film capacitors such as dielectric loss, temperature coefficient of capacitance and breakdown voltage have been related to such fundamental quantities as atomic numbers and permittivities. This permits estimation of the properties of “new” dielectrics in thin film form and short lists of the best materials for ...

Dielectric Thin Films for Microcavity Applications
1996The considerable development of optical instruments leads, in turn, to various studies on interference thin films in order to master the manufacturing of surface coatings with prescribed optical properties as, for example, antireflection filters, laser cavity mirrors, narrow band filters, and so on...

Mechanical properties of dielectric thin films
Optical Interference Coatings, 1997Stress in thin films deposited by Reactive Low-Voltage Ion Plating (RLVIP) and conventional reactive evaporation (RE) process is studied in air and at room temperature. Multilayers stacks are considered and the interactions layer to layer turn out to have no effect as regards to the final bending.

Dielectric properties of ultra-thin films
AIP Conference Proceedings, 2005A novel evaluation method of a dielectric constant is proposed with the use of first‐principles calculations for the ground states in external eletrostatic fields, which is applicable to ultrathin films. The optical dielectric constant evaluated at the innermost region of the film approaches a constant value near to the experimental bulk dielectric ...
